Redetermination of Tetra­kis­(methylammonium) Hexa­chloroindate Chloride

The structure of tetrakis(methylammonium) hexachloroindate chloride, originally determined by Schlimper & Ziegler [Z. Naturforsch. Teil B (1972), 27, 377-379], has been redetermined and compared with the redetermination of Knop et al. [Can. J. Chem. (1987), 65, 1527-1555].

A New Ammonium Manganese(II) Gallium Phosphate Hydrate: NH₄[MnGa₂(PO₄)₃(H₂ O)₂]

The title compound, ammonium manganese(II) digallium tris(phosphate) dihydrate, consists of GaO₅, MnO₆ and PO₄ polyhedra linked to form a three-dimensional framework containing channels in which the NH₄⁺ cations reside.

Penta­carbonyl(1,2,3,4-tetra­cyclo­hexylcyclo­tetraphosphane-P)chromium(0), [Cr(CO)₅(chexP)₄]

The Cr octahedron is slightly distorted with the bond Cr-C opposite the P atom shortened to 1.845 (2) Å. The geometry of the P₄ ring is not influenced by the addition of Cr(CO)₅ and the cyclohexyl residues reveal an all-trans configuration.

Chloro[5,10,15,20-tetra­kis­(penta­fluoro­phenyl)porphinato]iron(III) 0.57-Toluene Solvate

The title compound was structurally characterized in an attempt to relate molecular structure properties with oxidative catalytic and high-affinity ligand-binding properties.

(E)-3,4-Diiso­propyl-2,5-di­methylhex-3-ene at 125K

The title compound belongs to the family of sterically crowded alkenes. The molecule has a normal C3-C4 double-bond length of 1.3686 (14) Å and the torsion angles around this bond are in good agreement with the results of force-field calculations.

(±)-(1S)-2-(2-Methyl-1,3-dioxolan-2-yl)-1-[(1S)-2-methylene­cyclo­propyl]-1-ethyl 4-Nitrobenzoate

The structure of the p-nitrobenzoate title compound was required for stereochemical assignments of the precursor alcohol which was used in the stereoselective synthesis of the natural product paeonilactone B.

(1-Methylimidazole-N³)tri­phenylboron

The addition compound of 1-methylimidazole with triphenylboron contains an approximately tetrahedrally coordinated B atom, with a B-N distance of 1.628 (5) Å and B-C bond lengths averaging 1.628 Å.

(3S,4S,4aR,10aS)-5-Acetyl-3,4,4a,5,6,7,10,10a-octa­hydro-8-meth­oxy-7-methyl-6-oxo-2H-pyrano[3,2-g]pteridine-3,4-diyl Di­acetate

The structure and stereochemistry of the title compound, the enantiomer of the compound reported previously by Low et al. [Acta Cryst. (1995), C51, 2141-2143], are reported.

Copper–Zinc Oxide Catalysts. VII. Zn(NH₃)_0.7(H₂ O)_0.3Cu(CN)₃

The structure of a new Cu-Zn bimetallic compound, poly[ammineaqua-di-μ₂-cyano-μ₃-cyano-copper(I)zinc(II)], is built up of infinite double sheets. Each sheet corresponds to a hexagonal network, with Zn and Cu atoms occupying alternate corners of the hexagons and cyano groups forming the edges. The sheets are connected into pairs by weaker Cu-C bonds completing the trigonal pyramidal coordination geometry of copper(I).

Barium Cobalt Phosphate, BaCo₂(PO₄)₂

BaCo₂(PO₄)₂ contains BaO₁₂ polyhedra, CoO₆ octahedra and PO₄ tetrahedra. Edge-sharing octahedra are a feature of its layered crystal structure which is isostructural with that of BaNi₂(AsO₄)₂.

K₆[As₆V₁₅O₄₂(H₂O)].6H₂O

The structure determination of K₆[As₆V₁₅O₄₂(H₂O)].6H₂O shows the heteropolyanion to have D₃ symmetry.

Inversion Symmetry in the Spin-Peierls Compound α'-NaV₂O₅

Single crystals of NaV₂O₅ are found to be centrosymmetric. The structure consists of edge- and corner-sharing V₂O₅ square pyramids. This structure allows only one V position in the asymmetric unit and V is therefore non-integer valent.

Cobalt Lithium Orthoborate, LiCoBO₃

The structure of cobalt lithium orthoborate, LiCoBO₃, is isotypic with those of LiMgBO₃, LiMnBO₃ and LiZnBO₃. It is built up from CoO₅ trigonal bipyramids, LiO₄ tetrahedra and BO₃ planar groups.

A Cobalt Aluminophosphate with Encapsulated Ethylenedi­amine: Co_0.65Al_0.35PO₄.0.5NH_2.65CH₂CH₂NH_2.65

A cobalt-substituted aluminophosphate, Co_0.65Al_0.35PO₄, with the zeolite gismondine topology encapsulating hydrogen-bonded (O⋯N) ethylenediamine is reported.
