Chechen President Ramzan Kadyrov said that unmanned aerial vehicles attacked the territory of the Russian University of Special Forces named after V. V. Putin (RUS) in the city of Gudermes. The attack took place on the morning of Tuesday, October 29. Kadyrov did not specify the number of drones involved. According to the Chechen President, the roof of the empty building caught fire as a result of the attack. No casualties were reported, the fire was quickly extinguished. The activities of the university have not been suspended, all services are operating as usual, Kadyrov said.

Russia's fibre optic controlled Knyaz Vandal (Prince Vandal) drone struck a column of the Armed Forces of Ukraine (AFU) in the Kursk region of Russia. The attack was captured on video. The recording shows the drone flying at high speed over an asphalt road. It slows down and descends slightly when approaching an intersection. Several Ukrainian vehicles with ammunition can be seen driving in its direction. Knyaz Vandal flies up to one of the vehicles and crashes into it to explode.  Fiber optic controlled UAVs are a revolutionary weapon. According to military analyst and co-founder of Vatfor information and analytical project, Sergey Poletayev, drones controlled via fibre optic appeared as part of the scientific and technological revolution. The invention of such drones can be compared to the advent of artillery.

The first launch of the Angara-A5 heavy launch vehicle from the newly built launch complex at the Vostochny Cosmodrome was aborted two minutes before lift off. The rocket with the Orion upper stage and test payload was supposed to take off for the first time from Vostochny on Tuesday, April 9, at 12:00. The launch was postponed. The launch of the Angara rocket was postponed till Wednesday, April 10, Roscosmos chief Yuri Borisov said.

The West has been cutting its funding for Ukraine. Next year loans remain doubtful. European heavyweights have announced a reduction in funding for Ukraine. France, which promised 3 billion euros in aid to Ukraine this year, has cut it by 1 billion, or by one-third. This is due to budget problems — budget deficit for 2024 may amount to about six percent of France's GDP, which is unacceptable according to EU rules. French Defense Minister Sebastien Lecornu clarified in an interview with Politico that he did not plan to request additional funds for Kyiv from parliament until the end of this year.

Olaf Scholz's nerves gave out after Trump's victory. By saving Ukraine, the German Chancellor has ruined the ruling coalition of Germany and will now build it with the CDU, putting Germany's problems aside. Scholz ruins ruling coalition by saving Zelensky Germany's ruling coalition fell apart on Wednesday, November 6, after which Chancellor Olaf Scholz (SPD) fired Finance Minister Christian Lindner, who represented the Free Democratic Party (FDP) in the "traffic light" coalition. Three other FDP ministers resigned soon afterwards. Scholz plans to hold early elections in March, and his government will operate in a minority until then. The leader of the opposition CDU party, Friedrich Merz, demands that elections be scheduled for January.

Cosmonaut candidate Andrei Babkin, who was dismissed from his flight position in September due to a runny nose, wrote a letter to Russian President Vladimir Putin. In his address to the head of state, Babkin wrote that he would like independent experts to assess his health condition. In response, the Roscosmos Cosmonaut Training Center (CTC) said that an extended consultation was held on July 12. Members of the ENT section of the Main Medical Commission, as well as specialists who had previously treated the cosmonaut, were present at the meeting. As a result, no grounds were found for revising the previous medical conclusion in relation to the cosmonaut candidate.

War correspondent Yevgeny Poddubny, who was injured in an attack by the Armed Forces of Ukraine in the Kursk region, was hospitalised in serious condition to a regional clinical hospital. In the morning of August 8, Poddubny was taken to the Sklifosovsky Institute of Emergency Medicine in Moscow, the Health Department said. After the attack, the journalist was immediately placed in the anti-shock department, given intensive therapy and then transferred to intensive care. Specialists from leading federal clinics make every effort to save the man's life.

Russian President Vladimir Putin presented a rare copy of the Koran to a new mosque in Grozny, the capital of Chechnya, the Grozny State Television and Radio Broadcasting Company said on Telegram. The head of state visited Chechnya on August 20. According to the channel, the Koran book presented by Putin is decorated with a gold ornament and inlaid with precious stones. The Mufti of the republic, Salah Mezhiyev, thanked the Russian leader on behalf of the people of Chechnya.

Russian President Vladimir Putin took part in the ceremony to launch the Chukotka nuclear icebreaker built at the Baltic Shipyard in St. Petersburg. Putin participated from Moscow via video link. The footage shows the head of state giving the command "Launch cleared!" A bottle of champagne was traditionally smashed against the side of the vessel before launch. Three best workers of the Baltic Shipyard cut the detent that secured the ship to the land. The multi-ton vessel then slowly slid along the rails into the water.

Russia's refusal to pay $50 billion to former Yukos shareholders will lead to new investigations.On March 31, the Moscow City Court will consider an appeal, which was filed against the ruling to pay $35 million to former Yukos shareholder Alexey Golubovich by his ex-wife Olga Mirimskaya. Allegedly, she received the money for the sale of Yukos shares 15 years ago, and her ex-husband asked for his share as part of the divorce proceedings that have been ongoing for the last ten years. These are unusual demands as Mirimskaya has never owned shares in the oil company. In addition, Golubovich was not only its shareholder, but also served as the director for strategic planning and corporate finance at OAO NK Yukos and was aware of all information related to the financial dealings of the oil giant. A journalistic investigation conducted by Pravda.Ru showed that Alexey Golubovich likely still works in close collaboration with other ex-owners of Yukos. Alexey Golubovich, a former shareholder of Yukos oil company, and Olga Mirimskaya, the chairwoman of the Board of Directors of BKF Bank, divorced in 2012, but the litigation over the division of their marital property continues to this day. Olga Mirimskaya is the founder of the Russian Product Company. She is also President of BKF Bank. Mirimskaya is charged with giving a bribe — two vehicles worth a total of 3.25 million rubles — to Yury Nosov, an investigator at the Moscow Region Department of the Investigative Committee in 2017. He handled the case, in which she appeared as a victim in connection with the kidnapping of her daughter. Nosov and Mirimskaya were arrested in the bribery case. They plead not guilty, claiming that the case has been initiated under false pretences with malicious intent. "According to the defendant, the case was initiated by Alexey Golubovich, as well as by her former common-law partner Nikolai Smirnov, a co-owner of the Golden Crown payment system, as an act of revenge for the return of her daughter, in order to seize her property," Mirimskaya's lawyer Alexander Chernov said.

A Ukrainian truck driver was killed in Germany because of his words about Russian President Vladimir Putin, Bild wrote. "During a fight on a parking lot in front of a sawmill in Oberroth [in the federal state of Baden-Württemberg], three truck drivers apparently killed a colleague of theirs on Saturday evening at around 8:15 p.m. They were arguing about Russia's role in the conflict in Ukraine,” the newspaper said. The Ukrainian citizen was 34 years old. The men were drinking alcoholic beverages at the time when the incident occurred. The police detained three of his colleagues, each of whom is suspected of the murder. One of them is a citizen of Uzbekistan, two others are from Eastern European countries.

The structures of nine hexa­methyl-[1,1'-bi­phenyl]-4,4'-di­ammonium (HMB) salts are described

Hydraulic fracking exposes shale plays to acidic hydraulic fracking fluid (HFF), releasing toxic uranium (U) along with the desired oil and gas. With no existing methods to ensure U remains sequestered in the shale, this study sought to add organic ligands to HFF to explore potential U retention in shale plays. To test this possibility, incubations were set up in which uranyl acetate and one organic bipyridine ligand (either 2,2'-, 2,3'-, 2,4'-, or 4,4'-bipyridine) were added to pristine HFF as the crystallization medium. After several months and complete evaporation of all volatiles, bulk yellow crystalline material was obtained from the incubations, three of which yielded crystals suitable for single-crystal analysis, resulting in two novel structures and a high-quality structure of a previously described compound. The UO2VI acetate complexes bis(acetato-κ2O,O')(2,2'-bipyridine-κ2N,N')dioxidouranium(VI), [U(C2H3O2)2O2(C10H8N2)2] or [2,2'-bipyridine]UVIO2(CH3CO2)2, (I), and bis(acetato-κ2O,O')(2,4'-bipyridine-κN1')dioxidouranium(VI), [U(C2H3O2)2O2(C10H8N2)2] or [2,4'-bipyridine]2UVIO2(CH3CO2)2, (III), contain eight-coordinate UVI in a pseudo-hexagonal bipyramidal coordination geometry and are molecular, packing via weak C—H...O/N interactions, whereas catena-poly[bis(2,3'-bipyridinium) [di-μ-acetato-μ3-hydroxido-μ-hydroxido-di-μ3-oxido-hexaoxidotriuranium(VI)]–2,3'-bipyridine–water (1/1/1)], (C10H9N2)2[U3(C2H3O2)2O8(OH)2]·C10H8N2·H2O or {[2,3'-bipyridinium]2[2,3'-bipyridine][(UVIO2)3(O)2(OH)2(CH3CO2)2·H2O]}n, (II), forms an ionic one-dimensional polymer with seven-coordinate pentagonal bipyramidal UVI centers and hydrogen-bonding interactions within each chain. The formation of these crystals could indicate the potential for bipyridine to bind with U in shale during fracking, which will be explored in a future study via ICP-MS (inductively coupled plasma mass spectrometry) analyses of U concentration in HFF/bipyridine/shale incubations. The variation seen here between the molecular structures may indicate variance in the ability of bipyridine isomers to form complexes with U, which could impact their ability to retain U within shale in the context of fracking.

A chiral nickel(II) Schiff base complex derived from 2-hy­droxy­benzo­phenone and (1S,2S)-1,2-di­phenyl­ethyl­enedi­amine shows a λ conformation of the central di­amine chelate ring. The substituents on the C&z-dbnd;N carbon atoms significantly affect the circular dichroism spectra.

In the title compound, [Cu2(L)2]·2CH2Cl2, the CuII ions coordinate two (S,O)-chelating aroyl­thio­urea moieties of doubly deprotonated furan-2,5-di­carbonyl­bis­(N,N-di­ethyl­thio­urea) (H2L) ligands. The coordination geometry of the metal centers is best described as a flat isosceles trapezoid with a cis arrangement of the donor atoms.

Crystallization of the title compound, fac-[ReBr(ppt-OMe)(CO)3] (ppt-OMe = C15H12N2OS), from CH2Cl2/n-pentane (1:5 v/v) at room temperature gave two polymorphs, which crystallize in monoclinic (P21/c; α form) and orthorhombic (Pna21; β form) space groups. The ReI complex molecules in either polymorph adopt a six-coordinate octahedral geometry with three facially-oriented carbonyl ligands, one bromido ligand, and two nitrogen atoms from one chelating ligand ppt-OMe. In the crystal, both polymorph α and β form di-periodic sheet-like architectures supported by multiple hydrogen bonds. In polymorph α, two types of hydrogen bonds (C—H...O) are found while, in polymorph β, four types of hydrogen bonds (C—H...O and C—H...Br) exist.

Reaction between equimolar amounts of 3,3,3',3'-tetraethyl-1,1'-(furan-2,5-dicarbonyl)bis(thiourea) (H2L) and CuCl2·2H2O in methanol in the presence of the supporting base Et3N gave rise to a neutral dinuclear complex bis[μ-3,3,3',3'-tetraethyl-1,1'-(furan-2,5-dicarbonyl)bis(thioureato)]dicopper(II) dichloromethane disolvate, [Cu2(C16H22N4O3S2)2]·2CH2Cl2 or [Cu2(L)2]·2CH2Cl2. The aroylbis(thioureas) are doubly deprotonated and the resulting anions {L2–} bond to metal ions through (S,O)-chelating moieties. The copper atoms adopt a virtually cis-square-planar environment. In the crystal, adjacent [Cu2(L)2]·2CH2Cl2 units are linked into polymeric chains along the a-axis direction by intermolecular coordinative Cu...S interactions. The co-crystallized solvent molecules play a vital role in the crystal packing. In particular, weak C—Hfuran...Cl and C—Hethyl...Cl contacts consolidate the three-dimensional supramolecular architecture.

The title compound, [Ni(C40H30N2O2)] (1), with an optically active Schiff base ligand derived from 2-hydroxybenzophenone and (1S,2S)-1,2-diphenylethylenediamine, was crystallized as the solvent-free and ethanol solvate forms (1 and 1·2C2H5OH). In both structures, the two phenyl groups on the stereogenic centers of the O,N,N,O-tetradentate ligand are axially oriented, and the conformation of the central diamine chelate ring is λ. The circular dichroism (CD) spectra of 1 and the analogous nickel(II) complex [Ni(C30H26N2O2)] (2) in solution show partially similar patterns in the 350–450 nm range, but are mirror images in the longer wavelength region (450–650 nm). In the latter region, the sign of CD for these complexes is sensitive to the substituents on the C=N carbon atoms (phenyl for 1 and methyl for 2) rather than the diamine chelate ring conformation.

The title compound, [RuCl2(C25H22P2)2] or [RuCl2(dppm)2] (dppm = bis­(di­phenyl­phosphan­yl)methane, C25H22P2) crystallizes as two half-mol­ecules (completed by inversion symmetry) in space group Poverline{1} (Z = 2), with the RuII atoms occupying inversion centers at 0,0,0 and 1/2, 1/2, 1/2, respectively. The bidentate phosphane ligands occupy equatorial positions while the chlorido ligands complete the distorted octa­hedral coordination spheres at axial positions. The bite angles of the phosphane chelates are similar for the two mol­ecules [(P—Ru—P)avg. = 71.1°], while there are significant differences in the twisting of the methyl­ene backbone, with a distance of the methyl­ene C atom from the RuP4 plane of 0.659 (2) and 0.299 (3) Å, respectively, and also for the phenyl substituents for both mol­ecules due to variations in weak C—H⋯Cl inter­actions.

In the title mol­ecule, C21H15N3OS, the C5=C6 double bond in the central enone group adopts a trans configuration. The dihedral angle between planes of the thia­zole and pyrazole rings is 6.6 (2)°. In the crystal, pairs of C—H⋯O hydrogen bonds generate inversion dimers and another pair of C—H⋯N hydrogen bonds link the dimers into chains propagating along a-axis direction.

The mol­ecular structure of the solvated title salt, (C21H25N2)2[Fe2(C14H10S2)4]·2C3H7NO reveals that the anion is situated on a crystallographic inversion center in the triclinic space group Poverline{1}. The title compound crystallizes utilizing a network of weak π-stacking inter­actions of phenyl rings pertaining to the di­thiol­ene unit. Moreover, the acidic imidazolium H atoms [N—C(H)—N] display non-classical hydrogen-bonding inter­actions of the C—H⋯O type to the oxygen atoms of the N,N-dimethyl formamide solvent, and hydrogen atoms on the backbone of imidazolium rings display weak C—H⋯S inter­actions with the di­thiol­ene sulfur atoms.

In the paper by Oliveira et al. [IUCrData (2023), 8, x230971], there was an error in the name of the first author.

In the title triazole-based N-heterocyclic carbene rhodium(I) cationic complex with a tetra­fluorido­borate counter-anion, [Rh(C8H12)(C8H15N3)(C18H15P)]BF4, which crystallizes with two cations and two anions in the asymmetric unit, the Rh center has a distorted square-planar coordination geometry with expected bond distances. Several nonclassical C—H⋯F hydrogen-bonding inter­actions help to consolidate the packing. Two of the F atoms of one of the anions are disordered over adjacent sites in a 0.814 (4):0.186 (4) ratio.

The title compound, C14H12O4, comprises of two crystallographically independent mol­ecules in the asymmetric unit, linked via C—H⋯O inter­actions to form dimeric entities. The allylic groups are twisted out of the phenyl planes with dihedral angles varying between 7.92 (13) and 25.42 (8)°. In the crystal, the packing follows a zigzag pattern along the c-axis direction. The absolute configuration of the sample could not be determined reliably.

The title compound, C16H17BrO2S, crystallizes as the erythro (RR/SS) isomer of a pair of sulfones that were diastereomeric due to chirality of the α-carbon atoms on the sulfone sulfur atom. The structural analysis was pivotal in showing that the 1,3 elimination reactions of these compounds, which lead to substituted stilbenes, occur with inversion at each asymmetric carbon atom. In the crystal, C—H⋯Br and C—H⋯O hydrogen bonds link the mol­ecules into a tri-periodic inter­molecular network.

The title compound, C13H10FNO2, was obtained by the reaction of 2-bromo-4-fluoro­benzoic acid with aniline. There are two independent mol­ecules, A and B, in the asymmetric unit, with slight conformational differences: the dihedral angles between the aromatic rings are 55.63 (5) and 52.65 (5)°. Both mol­ecules feature an intra­molecular N—H⋯O hydrogen bond. In the crystal, the mol­ecules are linked by pairwise O—H⋯O hydrogen bonds to form A–B acid–acid dimers and weak C—H⋯F inter­actions further connect the dimers.

The title compound, C13H10BrNO2, was obtained by the reaction of 2,5-di­bromo­benzoic acid and aniline. The mol­ecule is twisted with a dihedral angle between the aromatic rings of 45.74 (11)° and an intr­amolecular N—H⋯O hydrogen bond is seen. In the crystal, pairwise O—H⋯O hydrogen bonds generate carb­oxy­lic acid inversion dimers.

In the title compound, C26H18BrN, the dihedral angles between the anthracene ring system and the phenyl rings are 89.51 (14) and 74.03 (15)°. In the extended structure, a weak C—H⋯Br inter­action occurs, which generates [100] chains, but no significant π–π or C—H⋯π inter­actions are observed.

The title mol­ecule, C12H15NO5, is a methyl carbamate derivative obtained by reacting (R)-2-phenyl­glycinol and methyl chloro­formate, with calcium hydroxide as heterogeneous catalyst. Supra­molecular chains are formed in the [100] direction, based on N—H⋯O hydrogen bonds between the amide and carboxyl­ate groups. These chains weakly inter­act in the crystal, and the phenyl rings do not display significant π–π inter­actions.

The mol­ecular structure of 2-ferrocenyl-2-[(2-ferrocenylethen­yl)(morpholin-4-yl)meth­yl]-1,3-di­thiol­ane, [Fe2(C5H5)2(C19H21NOS2)] or C29H31Fe2NOS2, has the ferrocenyl fragments in a trans disposition with respect to the vinyl group. One of the methyl­ene groups is disordered over two sites with occupancies of 0.782 (13):0.218 (13). In the crystal, cyclo­penta­dienyl-C—H⋯O(morpholin­yl) inter­actions feature within helical chains parallel to the c-axis direction. The chains are connected by methyl­ene- and cyclo­penta­dienyl-C—H⋯O(cyclo­penta­dien­yl) inter­actions.

The mol­ecule of the title NCNHCS pincer N-heterocyclic carbene palladium(II) complex, [PdBr(C21H25N3S)]Br, exhibits a slightly distorted square-planar coordination at the palladium(II) atom, with the five-membered chelate ring nearly planar. The six-membered chelate ring adopts an envelope conformation. Upon chelation, the sulfur atom becomes a stereogenic centre with an RS configuration induced by the chiral carbon of the precursor imidazolium salt. There are intra­molecular C—H⋯Br—Pd hydrogen bonds in the structure. The two inter­stitial Br atoms, as the counter-anion of the structure, are both located on crystallographic twofold axes and are connected to the complex cations via C—H⋯·Br hydrogen bonds.

In the title compound, C26H18BrN, the central benzene ring makes dihedral angles with its adjacent anthracene ring system and pendant benzene ring of 87.49 (13) and 62.01 (17)°, respectively. The N—H moiety is sterically blocked from forming a hydrogen bond, but weak C—H⋯π inter­actions occur in the extended structure.

The title compound {systematic name: (2S)-2-aza­niumyl-3-[(2-carb­oxy­ethane)­sulfon­yl]propano­ate}, C6H11NO6S, forms enanti­opure crystals in the monoclinic space group P21 and exists as a zwitterion, with a protonated α-amino group and a deprotonated α-carboxyl group. Both the carboxyl groups and the amino group are involved in an extensive multicentered inter­molecular hydrogen-bonding scheme. In the crystal, the diperiodic network of hydrogen bonds propagates parallel to (101) and involves inter­connected heterodromic R43(10) rings. Electrostatic forces are major contributors to the structure energy, which was estimated by DFT calculations as Etotal = −333.5 kJ mol−1.

In the title compound, [Mn(C68H44N12O4)(C5H8N2)]·2C6H5Cl, the central MnII ion is coordinated by four pyrrole N atoms of the porphyrin core in the basal sites and one N atom of the 2,5-di­methyl­imidazole ligand in the apical site. Two chloro­benzene solvent mol­ecules are also present in the asymmetric unit. Due to the apical imidazole ligand, the Mn atom is displaced out of the 24-atom porphyrin mean plane by 0.66 Å. The average Mn—Np (p = porphyrin) bond length is 2.143 (8) Å, and the axial Mn—NIm (Im = 2,5-di­methyl­imidazole) bond length is 2.171 (8) Å. The structure displays inter­molecular and intra­molecular N—H⋯O, N—H⋯N, C—H⋯O and C—H⋯N hydrogen bonding. The crystal studied was refined as a two-component inversion twin.

The title compound, [Ir(C8H12)(C8H15N3)(C18H15P)]BF4, a new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra­fluorido­borate counter-anion, crystallizes with two cations and two anions in the asymmetric unit of space group Pc. The Ir centers of the cations have distorted square-planar conformations, formed by a bidentate (η2 + η2) cyclo­octa-1,5-diene (COD) ligand, an N-heterocyclic carbene and a tri­phenyl­phosphane ligand with the NHC carbon atom and P atom being cis. In the extended structure, non-classical C–H⋯F hydrogen bonds, one of which is notably short (H⋯F = 2.21 Å), link the cations and anions. The carbon atoms of one of the COD ligands are disordered over adjacent sites in a 0.62:0.38 ratio.
