Tris(glycine)scandium(III) Triperchlorate: a Space-Group Correction

The title complex consists of infinite positively charged [Sc₂(Gly)₆]_n (Gly = glycine) chains and ClO₄⁻ anions. The Sc³⁺ ions in the [Sc₂(Gly)₆]_n chains are linked by glycine molecules and are octahedrally coordinated by glycine O atoms.

Bis(tetra­ethylammonium) tetra-μ-carbonyl-icosa­carbonylhexairondithallate(2 Fe—Fe)(8 Fe—Tl)(2–)

This compound belongs to a family of dimeric clusters formed through bonding of electron-rich iron carbonyls to electron-deficient thallium. Pressurization under CO of the thallium-iron carbonyl [Et₄N]₂[Fe₄Tl₂(CO)₁₆] yielded crystals of [Et₄N]₂[Fe₆Tl₂(CO)₂₄], which crystallizes in the orthorhombic centrosymmetric space group Cmca.

2-Pyridine­carboxylic Acid

The crystal structure of 2-pyridinecarboxylic acid was redetermined to confirm the space group C2/c. However, a solid-state high resolution ¹⁵N CP-MAS NMR study indicated that neutral molecules and zwitterions are arranged alternately within local non-centrosymmetric domains.

sp-9-(o-tert-Butylphenyl)-3-(methylthio)fluorene: a Major Rearrangement Product from the Facile Uncatalyzed Decomposition of ap-9-(o-tert-Butylphenyl)-9-(methylthio)fluorene

On short-term heating, highly strained ap-9-(o-tert-butylphenyl)-9-(methylthio)fluorene underwent facile cleavage of the C-S bond. Migration of the methylthio group produced sp-9-(o-tert-butylphenyl)-3-(methylthio)fluorene as the major product. Its structure is much less distorted than that of the ap starting material.

trans-(R,R)-2,2'-(Cyclo­penta-1,2-diyl)di­phenyl Bis[(R)-O-methylmandelate]

The title compound crystallizes with two independent molecules per asymmetric unit. The molecules assume slightly different conformations. The crystallographically unique molecules stack in columns along the b axis. Close C-H⋯O contacts are observed between molecules related by a twofold screw axis. The absolute configuration was established by internal comparison with the (R)-(−)-O-methyl mandelic acid moiety.

Disodium Zinc Pyrophosphate and Disodium (Europium) Zinc Pyrophosphate

Disodium zinc diphosphate may be doped with europium(III) to produce a red-emitting material, Na_1.94Eu_0.02ZnP₂O₇. Determination of the single-crystal X-ray structures of the doped and undoped forms shows them to be isostructural, with Eu^III occupying a site of mm symmetry.

KAg₅S₃

KAg₅S₃ contains a combination of linear and trigonal planar coordination of Ag by S atoms, resulting in a channeled framework filled with K⁺ cations.

Pentaammine­nitrocobalt(III) Dichloride at Pressures of 0.24, 0.52, 1.25, 1.91 and 3.38 GPa

The structure of [Co(NO₂)(NH₃)₅]Cl₂ has been refined anisotropically from data collected at 0.24, 0.52, 1.25, 1.91 and 3.38 GPa in a diamond anvil cell. For comparison, the structure of the same crystal in the same diamond anvil cell was also refined at ambient pressure.

(NH₄)Zn₂(PO₄)(HPO₄)

This new ammonium zinc phosphate, which is isostructural with KZn₂(PO₄)(HPO₄), consists of corrugated anionic layers of ZnO₄ and PO₄ tetrahedra sharing vertices. Trigonally coordinated O atoms are present in these layers.
