The title compound, [RuCl2(C33H43N3O)], is an example of a new generation of N,N-dialkyl ruthenium catalysts with an N—Ru coordination bond as part of a six-membered chelate ring. The Ru atom has an Addison τ parameter of 0.244, which indicates a geometry inter­mediate between square-based pyramidal and trigonal–bipyramidal. The complex shows the usual trans arrangement of the two chlorides, with Ru—Cl bond lengths of 2.3515 (8) and 2.379 (7) Å, and a Cl—Ru—Cl angle of 158.02 (3)°. One of the chlorine atoms and the atoms of the 2-meth­oxy-N-methyl-N-[(2-methyl­phen­yl)meth­yl]ethane-1-amine group of the title complex display disorder over two positions in a 0.889 (2): 0.111 (2) ratio.

Crystal structure of a water oxidation catalyst solvate with composition (NH4)2[FeIV(L-6H)]·3CH3COOH (L = clathrochelate ligand)

The synthetic availability of mol­ecular water oxidation catalysts containing high-valent ions of 3d metals in the active site is a prerequisite to enabling photo- and electrochemical water splitting on a large scale. Herein, the synthesis and crystal structure of di­ammonium {μ-1,3,4,7,8,10,12,13,16,17,19,22-dodeca­aza­tetra­cyclo­[8.8.4.13,17.18,12]tetra­cosane-5,6,14,15,20,21-hexa­onato}ferrate(IV) acetic acid tris­olvate, (NH4)2[FeIV(C12H12N12O6)]·3CH3COOH or (NH4)2[FeIV(L–6H)]·3CH3COOH is reported. The FeIV ion is encapsulated by the macropolycyclic ligand, which can be described as a dodeca-aza-quadricyclic cage with two capping tri­aza­cyclo­hexane fragments making three five- and six six-membered alternating chelate rings with the central FeIV ion. The local coord­ination environment of FeIV is formed by six deprotonated hydrazide nitro­gen atoms, which stabilize the unusual oxidation state. The FeIV ion lies on a twofold rotation axis (multiplicity 4, Wyckoff letter e) of the space group C2/c. Its coordination geometry is inter­mediate between a trigonal prism (distortion angle φ = 0°) and an anti­prism (φ = 60°) with φ = 31.1°. The Fe—N bond lengths lie in the range 1.9376 (13)–1.9617 (13) Å, as expected for tetra­valent iron. Structure analysis revealed that three acetic acid mol­ecules additionally co-crystallize per one iron(IV) complex, and one of them is positionally disordered over four positions. In the crystal structure, the ammonium cations, complex dianions and acetic acid mol­ecules are inter­connected by an intricate system of hydrogen bonds, mainly via the oxamide oxygen atoms acting as acceptors.

In the title mol­ecule, C21H23N3O3, the imidazolidine ring slightly deviates from planarity and the morpholine ring exhibits the chair conformation. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds form helical chains of mol­ecules extending parallel to the c axis that are connected by C—H⋯π(ring) inter­actions. A Hirshfeld surface analysis reveals that the most important contributions for the crystal packing are from H⋯H (55.2%), H⋯C/C⋯H (22.6%) and H⋯O/O⋯H (20.5%) inter­actions. The volume of the crystal voids and the percentage of free space were calculated to be 236.78 Å3 and 12.71%, respectively. Evaluation of the electrostatic, dispersion and total energy frameworks indicates that the stabilization is dominated by the nearly equal electrostatic and dispersion energy contributions. The DFT-optimized mol­ecular structure at the B3LYP/6-311 G(d,p) level is compared with the experimentally determined mol­ecular structure in the solid state. Moreover, the HOMO–LUMO behaviour was elucidated to determine the energy gap.

Synthesis, crystal structure and properties of the trigonal–bipyramidal complex tris­(2-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II)

Reaction of Co(NCS)2 with 2-methyl­pyridine N-oxide in a 1:3 ratio in n-butanol leads to the formation of crystals of tris­(2-methyl­pyridine N-oxide-κO)bis­(thio­cyanato-κN)cobalt(II), [Co(NCS)2(C6H7NO)3]. The asymmetric unit of the title compound consists of one CoII cation two thio­cyanate anions and three crystallographically independent 2-methyl­pyridine N-oxide coligands in general positions. The CoII cations are trigonal–bipyramidally coordinated by two terminal N-bonding thio­cyanate anions in the trans-positions and three 2-methyl­pyridine N-oxide coligands into discrete complexes. These complexes are linked by inter­molecular C–H⋯S inter­actions into double chains that elongate in the c-axis direction. Powder X-ray diffraction (PXRD) measurements prove that all batches are always contaminated with an additional and unknown crystalline phase. Thermogravimetry and differential analysis of crystals selected by hand reveal that the title compound decomposes at about 229°C in an exothermic reaction. At about 113°C a small endothermic signal is observed that, according to differential scanning calorimetry (DSC) measurements, is irreversible. PXRD measurements of the residue prove that a poorly crystalline and unknown phase has formed and thermomicroscopy indicates that some phase transition occurs that is accompanied with a color change of the title compound.

Triclinic polymorph of bis­[2-methyl-3-(pyridin-2-yl)imidazo[1,5-a]pyridin-2-ium] tetra­chloridocadmium(II)

The crystal structure of the title organic–inorganic hybrid salt, (C13H12N3)2[CdCl4], (I), has been reported with four mol­ecules in the asymmetric unit in a monoclinic cell [Vassilyeva et al. (2021). RSC Advances, 11, 7713–7722]. While using two different aldehydes in the oxidative cyclization–condensation involving CH3NH2·HCl to prepare a new monovalent cation with the imidazo[1,5-a]pyridinium skeleton, a new polymorph was obtained for (I) in space group P1 and a unit cell with approximately half the volume of the monoclinic form. The structural configurations of the two crystallographically non-equivalent organic cations as well as the geometry of the moderately distorted tetra­hedral CdCl42– dianion show minor changes. In the crystal, identically stacked cations and tetra­chloro­cadmate anions form separate columns parallel to the a axis. The loose packing of the anions leads to a minimal separation of approximately 9.53 Å between the metal atoms in the triclinic form versus 7.51 Å in the monoclinic one, indicating that the latter is packed slightly more densely. The two forms also differ by aromatic stacking motifs. Similar to the monoclinic polymorph, the triclinic one excited at 364 nm shows an intense unsymmetrical photoluminescent band with maximum at 403 nm and a full width at half maximum of 51 nm in the solid state.

Crews Demolish Remaining Section Of Florida Condo As Storm Nears

Brian Mann | NPR

Updated July 4, 2021 at 10:53 PM ET

SURFSIDE, Fla. — Crews used explosives late Sunday night to demolish the remaining structure at Champlain Towers South in Surfside, Fla.

The heavily damaged condo building was knocked down at about 10:30 p.m. Eastern time.

The targeted blast caused the tower to fold and crumble, sending a large plume of dust and debris over a section of the beachside community. A crowd watching from a distance prayed as the building came down.

Before the structure was leveled, Miami-Dade County police urged residents who live nearby to remain indoors and shelter in place.

Miami-Dade County officials said removing the tower was an essential step so search and rescue teams could resume scouring the rubble pile for victims of the disaster.

Officials suspended recovery efforts on Saturday because of concerns about the danger posed by the unstable building.

"It will be safe to resume the search activities very shortly after the blast and that's when we'll resume it," said Miami-Dade County Mayor Daniella Levine Cava at a press conference Sunday evening.

Demolition of the tower was also accelerated because of Tropical Storm Elsa, which could hit South Florida with high winds and heavy rains as early as Monday.

Search efforts had been ongoing since the morning of June 24, when much of the 12-story condo complex suffered a "progressive collapse" and dozens of apartments were reduced to rubble in a matter of seconds.

The number of confirmed dead from the disaster remains at 24, with the number of people unaccounted for at 121.

Rep. Debbie Wasserman Schultz, D-Fla., told reporters Sunday the demolition of the remaining tower added to the sorrow for families who lived in the complex, destroying homes and possessions.

"So often demolitions of buildings are a spectacle, it's almost like a show," Schultz said. "This demolition is a tragic situation."

Local officials assured former residents and the public that everything possible had been done to rescue pets left behind in the structure.

"Folks can be comfortable we're not leaving anyone behind, including our beloved pets," Surfside Mayor Charles Burkett told reporters.

Multiple investigations are already underway into the cause of the collapse.

Documents acquired by NPR from an anonymous source show the condo association's board received warnings from an engineering firm beginning in 2018 that the structure needed extensive repairs.

A memo sent by the association to Champlain Towers South residents ahead of a May 2021 board meeting acknowledged the "desperate needs of the building."

Tropical Storm Elsa Is Lashing Cuba And Has Florida Next In Its Sights

Dan Charles | NPR

Updated July 5, 2021 at 11:33 AM ET

A tropical storm with 65-mile-an-hour winds is drenching Cuba, and is expected to reach Key West and the west coast of Florida within the next 48 hours.

The National Hurricane Center expects Tropical Storm Elsa to drop between 5 and 10 inches of rain on central and western Cuba, leading to significant flooding and mudslides. The storm probably will weaken somewhat as it crosses the island, but could strengthen again as it approaches Florida.

According to the Associated Press, Cuban officials evacuated 180,000 people as a precaution against the possibility of heavy flooding.

Most of those evacuated stayed at relatives' homes, others went to government shelters, and hundreds living in mountainous areas took refuge in caves prepared for emergencies. The storm had killed at least three people on other Caribbean islands before it reached Cuba

The National Weather Service says that the western coast of Florida, including Tampa Bay, can expect a storm surge that would lift water levels between two and four feet. Much of Florida could see heavy rainfall that could reach six inches in some places. The storm will then bring heavy rains to Georgia and the Carolinas later in the week.

Florida officials were worried that the storm could destabilize what was left of the condominium building that partially collapsed over a week ago. In order to avoid an uncontrolled collapse, they approved the demolition of the remaining portion of the building, which took place on Sunday night.

"The hurricane was coming, the potential for that building to fall on the pile with the victims in it was a tragic thought," Surfside Mayor Charles Burkett told NPR on Monday.

It's early in the hurricane season. The National Oceanic and Atmospheric Administration has predicted a busier-than-average Atlantic hurricane season, but it would be hard to top last year's, which set an all-time record with 30 named storms.

Tropical storms are fueled by warm water in the upper layers of the ocean, and ocean temperatures have been rising as heat is trapped by greenhouse gases.

Florida Condo Deaths Climb To 32 As Officials Try To Pinpoint The Number Of Missing

Joe Hernandez | NPR

Crews searching the building collapse site in Surfside, Fla., have discovered four more victims since Monday, bringing the death toll to 32. Authorities have identified 26 of the bodies.

Another 113 people were unaccounted for, though local officials said they had only been able to confirm that about 70 of those people were in the building at the time of the collapse nearly two weeks ago.

Detectives are continuing to follow up on reports submitted about possible victims in the partial collapse, but in some cases they have been unable to reach those who submitted the tips in the first place.

"People call anonymously. People call and don't leave return phone numbers. People call with partial information, not enough to really secure whether that person may or may not have been in the building," Miami-Dade County Mayor Daniella Levine Cava told reporters on Tuesday.

Some of the reports of possible victims are also incomplete, she said, including a name but no apartment number or no date of birth.

Levine Cava urged people who are missing loved ones to communicate with local authorities. She said there may also be victims of the collapse who have not been reported missing.

The rescue effort stopped briefly overnight due to lightning from a passing storm. Surfside Mayor Charles Burkett said high winds were hampering the cranes moving heavy debris from the collapse site.

Lt. Gov. Jeanette Nuñez said Florida has declared a state of emergency ahead of Tropical Storm Elsa, which is expected to reach hurricane strength before making landfall Wednesday morning on the state's west coast.

This School District Erased All Holiday Names After Dropping Columbus Day

Some institutions have scrapped Columbus Day or switched to celebrating Indigenous Peoples' Day. One New Jersey school district came up with a new solution: eliminate all holiday names.; Credit: Olesya Semenov/EyeEm via Getty Images

Memorial Day. Thanksgiving. Labor Day.

You may be used to seeing your calendar punctuated by the various holidays that occur throughout the year.

But on one New Jersey school district's calendar, each one of these days will be listed, simply, as "day off."

It all started when the school board in Randolph Township voted to change Columbus Day to Indigenous Peoples' Day. Some residents were outraged, so the board said that instead it would wipe holiday names from the school calendar altogether while still observing the days off.

"The overwhelming majority of the township population feels that they've [Randolph Township school board members] grossly overstepped their bounds, that they're completely pushing their own personal, political ideologies," Randolph resident Tom Tatem told Fox News. He started a petition calling on school officials to resign.

Institutions across the country are wrestling with the question of what to do with Columbus Day.

Critics have derided the idea of celebrating the Italian explorer, who perpetrated violence on Native Americans when he arrived in the United States. Boosters say it is critical to recognize the contributions of Christopher Columbus, and that Italian-Americans have historically faced discrimination.

Some places have switched to marking Indigenous Peoples' Day in recognition of the Native Americans who occupied the United States long before European explorers like Columbus arrived.

Randolph Township arrived at a novel solution to this problem: eliminate every holiday name to avoid taking a side.

The goal appears to have been to sidestep the debate over Columbus Day, but the Randolph Township school system instead found itself squarely in it, and opponents of the move have called on school officials to resign.

The Randolph Board of Education is now scheduled to convene Monday for a special meeting to reconsider its plan to remove holiday names from the school calendar.

What's happening in New Jersey

In May, the Randolph school board voted unanimously to replace Christopher Columbus Day with Indigenous Peoples' Day.

Some parents grew angry with the decision, but instead of reverting back to the old calendar, the board moved in early June to scrap all holiday names from the school calendar, not giving preference to either one of the October celebrations.

"If we don't have anything on this calendar, then we don't have to have anyone [with] hurt feelings," Randolph school board member Dorene Roche said during a June 10 public meeting, according to NJ.com.

The backlash has only grown.

A petition calling on Randolph Township Schools superintendent Jennifer Fano and members of the board of education to resign has topped 4,000 signatures. "They represent everything that is wrong in education today and are completely incompetent in every aspect of their role," the petition says.

For its part, the school board acknowledged the public outcry but said its decision was misconstrued by some people.

A press release issued by the Randolph board of education on Sunday clarified that the holidays will still be observed as days off and that their decision was not meant to dishonor "the great veterans and the heroes" after which several of those holidays are named.

"These State, Federal and other holidays have not been cancelled or taken away by this Board of Education as some are falsely claiming," the board said. "Everyone is still encouraged to celebrate them in whatever way they deem appropriate."

Matthew Pfouts, director of communications and digital media for the Randolph Township Schools, told NPR the board has no further comment.

Changing views on holidays

On the national level, Columbus Day remains a federal holiday.

But a number of states, including Alaska and Virginia, as well as some cities either observe Indigenous Peoples' Day as a holiday or celebrate it in some way.

The movement away from Columbus Day has not come without controversy.

The New York City Department of Education tried to rename Columbus Day over objections and eventually settled on marking a holiday called "Italian Heritage Day/Indigenous People's Day," which drew its own set of critiques. New York Gov. Andrew Cuomo said it was wrong to make the two groups share one holiday.

There are also other efforts to recognize the role people of color played in American history.

This week, the Senate unanimously passed a bill to make Juneteenth — the day marking the end of slavery in the U.S. — a public holiday.
