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.

The title compound, [Fe(C84H52N12O4)Cl], crystallizes in space group C2/c. The central FeIII cation (site symmetry 2) is coordinated in a fivefold manner, with four pyrrole N atoms of the porphyrin core in the basal sites and one Cl atom (site symmetry 2) in the apical position, which completes a slightly distorted square-pyramidal environment. The porphyrin macrocycle shows a characteristic ruffled-shape distortion and the iron atom is displaced out of the porphyrin plane by 0.42 Å with the average Fe—N distance being 2.054 (4) Å; the Fe—Cl bond length is 2.2042 (7) Å. Inter­molecular C—H⋯N and C—H⋯O hydrogen bonds occur in the crystal structure.

The title compound, [Fe(C4H8O)4(H2O)2][Fe4Ga4(C2H6O2Si)Cl4(CO)15]·4C4H8O, consists of an iron(II) cation octa­hedrally coordinated by two water mol­ecules (trans) with four tetra­hydro­furans (THF) at equatorial sites. Two additional THF mol­ecules are hydrogen bonded to each of the water mol­ecules. The dianion of the title compound is an organometallic butterfly complex with a dimethyl siloxane core and two iron-gallium fragments. The lengths of the iron to gallium metal–metal bonds range from 2.3875 (6) to 2.4912 (6) Å.

The activation of C—C bonds by transition-metal com­plexes is of continuing inter­est and aceto­nitrile (MeCN) has attracted attention as a cyanide source with com­paratively low toxicity for organic cyanation reactions. A di­iron end-on μ-η1:η1-CN-bridged com­plex was obtained from a crystallization experiment of an open-chain iron–NHC com­plex, namely, μ-cyanido-κ2C:N-bis­{[(aceto­nitrile-κN)[3,3'-bis­(pyridin-2-yl)-1,1'-(methyl­idene)bis­(benzimidazol-2-yl­idene)]iron(II)} tris­(hexa­fluoro­phos­phate), [Fe2(CN)(C2H3N)2(C25H18N6)2](PF6)3. The cyanide appears to originate from the MeCN solvent by C—C bond cleavage or through carbon–hy­dro­gen oxidation.

The expansive scientific software ecosystem, characterized by millions of titles across various platforms and formats, poses significant challenges in maintaining reproducibility and provenance in scientific research. The diversity of independently developed applications, evolving versions and heterogeneous components highlights the need for rigorous methodologies to navigate these complexities. In response to these challenges, the SBGrid team builds, installs and configures over 530 specialized software applications for use in the on-premises and cloud-based computing environments of SBGrid Consortium members. To address the intricacies of supporting this diverse application collection, the team has developed the Capsule Software Execution Environment, generally referred to as Capsules. Capsules rely on a collection of programmatically generated bash scripts that work together to isolate the runtime environment of one application from all other applications, thereby providing a transparent cross-platform solution without requiring specialized tools or elevated account privileges for researchers. Capsules facilitate modular, secure software distribution while maintaining a centralized, conflict-free environment. The SBGrid platform, which combines Capsules with the SBGrid collection of structural biology applications, aligns with FAIR goals by enhancing the findability, accessibility, interoperability and reusability of scientific software, ensuring seamless functionality across diverse computing environments. Its adaptability enables application beyond structural biology into other scientific fields.

Reaction of FeCl2·4H2O with KSCN and 3-cyano­pyridine (pyridine-3-carbo­nitrile) in ethanol accidentally leads to the formation of single crystals of Fe(NCS)(Cl)(3-cyano­pyridine)4 or [FeCl(NCS)(C6H4N2)4]. The asymmetric unit of this compound consists of one FeII cation, one chloride and one thio­cyanate anion that are located on a fourfold rotation axis as well as of one 3-cyano­pyridine coligand in a general position. The FeII cations are sixfold coordinated by one chloride anion and one terminally N-bonding thio­cyanate anion in trans-positions and four 3-cyano­pyridine coligands that coordinate via the pyridine N atom to the FeII cations. The complexes are arranged in columns with the chloride anions, with the thio­cyanate anions always oriented in the same direction, which shows the non-centrosymmetry of this structure. No pronounced inter­molecular inter­actions are observed between the complexes. Initially, FeCl2 and KSCN were reacted in a 1:2 ratio, which lead to a sample that contains the title compound as the major phase together with a small amount of an unknown crystalline phase, as proven by powder X-ray diffraction (PXRD). If FeCl2 and KSCN is reacted in a 1:1 ratio, the title compound is obtained as a nearly pure phase. IR investigations reveal that the CN stretching vibration for the thio­cyanate anion is observed at 2074 cm−1, and that of the cyano group at 2238 cm−1, which also proves that the anionic ligands are only terminally bonded and that the cyano group is not involved in the metal coordination. Measurements with thermogravimetry and differential thermoanalysis reveal that the title compound decomposes at 169°C when heated at a rate of 4°C min−1 and that the 3-cyano­pyridine ligands are emitted in two separate poorly resolved steps. After the first step, an inter­mediate compound with the composition Fe(NCS)(Cl)(3-cyano­pyridine)2 of unknown structure is formed, for which the CN stretching vibration of the thio­cyanate anion is observed at 2025 cm−1, whereas the CN stretching vibration of the cyano group remain constant. This strongly indicates that the FeII cations are linked by μ-1,3-bridg­ing thio­cyanate anions into chains or layers.

The mol­ecular structure of tricarbon­yl[η4-6-exo-(tri­phenyl­phosphino)cyclo­hepta-2,4-dien-1-one]iron(0) tetra­fluoro­borate di­chloro­methane hemisolvate, [Fe(C28H22O4)(CO)3]BF4·0.5CH2Cl2, as determined by single-crystal X-ray diffraction is reported. The two independent tricarbon­yl[η4-6-exo-(tri­phenyl­phosphino)cyclo­hepta-2,4-dien-1-one] iron(0) cations and their corresponding anions form dimers, which constitute the asymmetric unit of the structure parallel to the (100) plane. Solid-state stability within that asymmetric unit as well as between neighboring dimeric units is afforded by C—H⋯O and C—H⋯F hydrogen bonds and C—H⋯π and Y—X⋯π (Y = B, C; X = F, O) inter­actions, which yield diperiodic sheets and a three-dimensional extended network.

Gloria Majiga-Kamoto, an activist from Malawi, is one of six recipients of the 2021 Goldman Environmental Prize. Majiga-Kamoto has been instrumental in implementing Malawi's ban on thin plastics.; Credit: /Goldman Environmental Prize

For Gloria Majiga-Kamoto, her great awakening to plastic pollution started with goats.

She was working for a local environmental NGO in her native Malawi with a program that gave goats to rural farmers. The farmers would use the goat's dung to produce low-cost, high-quality organic fertilizer.

The problem? The thin plastic bags covering the Malawian countryside.

"We have this very common street food, it's called chiwaya, and it's just really potato fried on the side of the road and it's served in these little blue plastics," Majiga-Kamoto says. "So because it's salty, once the goats get a taste of the salt, they just eat the plastic because they can't really tell that it's inedible. And they die because it blocks the ingestion system — there's no way to survive."

The goats were supposed to reproduce for the program, with the goat kids going on to new farmers. But because of plastic deaths the whole goat chain started falling apart.

"It was a lot of expectation from the farmers waiting to benefit. So you had this farmer who had this one goat and then they lost it. And that means that in that chain of farmers, that's obviously affected quite a number of farmers who won't get their turn."

For Majiga-Kamoto, her experience at the NGO with the plastic-eating goats was the moment it all changed. All of a sudden she started noticing how plastics were everywhere in the Malawian environment and food system — affecting people's livelihoods and health.

The fish in Lake Malawi were eating plastic trash. The country's cows were eating plastic. Researchers found that in one Malawi town 40% of the livestock had plastic in their intestines.

"We're choking in plastics," Majiga-Kamoto says, "And so what it means is that in one way or the other, we as humans are consuming these plastics."

Majiga-Kamoto was also seeing how plastics contributed to the growth of disease. Huge piles of plastic trash were blocking off Malawi's many waterways, creating pungent breeding grounds for mosquitoes that carry malaria and for bacteria that cause cholera.

The 30-year-old says she remembers a time when Malawians didn't rely so much on thin, single-use plastic. "I remember back in the day when we'd go to the market and buy things like fish, like dried fish, you'd get it in newspapers."

But thin plastics have taken off in the last decade or so as new manufacturers sprung up in Malawi, selling products like thin plastic bags at cheap prices that made them affordable and accessible even in the most undeveloped parts of the country. A 2019 UNDP funded report found that Malawi produces an estimated 75,000 tonnes of plastic a year, with 80% reportedly single-use plastic. Single-use plastic refers to bags, straws and bottles that can't be recycled, and thin plastic refers to plastic that's under 60 microns in thickness.

The proliferation of this thin plastic waste led to the Malawian government's 2015 decision to ban the production, distribution and importation of single-use thin plastic. But before the ban could go into full effect, Malawi's plastics manufacturing industry filed an injunction at the country's High Court. The ban stalled.

When Majiga-Kamoto and a group of her fellow environmental NGO-workers and activists heard about the injunction they were angry and frustrated. "It sort of caught our interest to say, 'Wait a minute, you mean that there's actually people in our society who think that this is not a problem and that we should actually continue to live this way?'"

Galvanized, Majiga-Kamoto led a group of local environmental activists and NGOs to actually implement the single-use plastics ban, organizing marches on the judiciary where the decision would be decided. She kept her job at her NGO, the Centre for Environmental Policy and Advocacy, and did this work on her own time.

She rejected the plastic industry's argument that the ban would hurt Malawi's economy — and even debated an industry lobbyist on TV.

Finally in 2019, after multiple injunctions filed by the plastics industry, the High Court ruled in favor of the single-use thin plastic ban. The following year the Malawian government began closing down illegal plastic manufacturers.

Last week Majiga-Kamoto was named one of the six winners of the 2021 Goldman Environmental Prize for her work on this issue. Michael Sutton, executive director of the Goldman Environmental Foundation, says Majiga-Kamoto's fight with the plastic lobby epitomizes the spirit of the prize. "She mustered the troops, the grassroots communities, to take on the government and big industry and won several times," Sutton says, "She not only won the ban in law, but is now holding the government's feet to the fire to enforce it."

And Majiga-Kamoto isn't letting up her pressure to uphold the single-use plastic ban anytime soon. Although she is trying to get some summer vacation time with her family — that is, if she isn't interrupted.

"I was just at the lake a couple of weeks ago and we were there just enjoying the beautiful lake and along come these pieces of plastic." Three plastic bags floated up closer to her, her son and her niece as they played in the water.

Majiga-Kamoto grabbed for the bags.

"My family was laughing to say, 'You shouldn't be working! You're at the lake!' And I'm like, 'But I can't just leave them in there!'"
