The New Mixed Lithium Tantalum Phosphide Li_8−xTa_xP₄ (x = 0.5)

The structure of Li_8−xTa_xP₄ (x = 0.5) has been refined in the space group Fm3m [a = 5.999(1)Å]. It has an anti-CaF₂ type structure in which the tetrahedral site is statistically occupied by Li and Ta atoms surrounded by P atoms.

Bis(tetra-n-butylammonium) Nonadecaoxohexamolybdenum(VI): a Redetermination at 148K

The structure of (C₁₆H₃₆N)₂[Mo₆O₁₉], originally determined at room temperature [Rheingold et al. (1993). Acta Cryst. C49, 756-758], has been redetermined at 148 K.

Octa­carbonyl(μ-di­cyclo­hexylphosphanido)(μ-tri­fluoro­methylmercury)dirhenium

This is a rare example of a trinuclear rhenium–mercury carbonyl cluster complex containing a bridging phosphanido ligand.

Octa­carbonylbis(μ-cyclo­hexylphosphanido)manganeserhenium

In contrast to related homonuclear complexes, the MnReP₂ ring in this complex is not planar and the C₆H₁₁ and H groups at both phosphanido bridges are in syn positions.

μ-Chloro-(μ-di­cyclo­hexylphosphanido)bis­[tri­carbonyl(tri­phenylphosphine)rhenium]

This is the first crystallographically characterized dirhenium carbonyl complex to contain one chloro and one phosphanido bridge.

Low-Temperature Structure of Lithium Bis(tri­methylsilyl)amide Etherate, {[LiO(CH₂CH₃)₂][N(Si(CH₃)₃)₂]}₂

The structure of lithium bis(trimethylsilyl)amide etherate has been determined at low temperature using improved metrical data.

β-Hy­droxy-N-(4-nitro­phenyl)phenethylamine

In the structure of this compound, inversion-related molecules form O-H⋯O hydrogen-bonded dimers which are linked by C-H⋯O intermolecular hydrogen bonds to form an infinite chain along the b direction. Molecules in different chains are linked by N-H⋯O hydrogen bonds.

Tri­phenylphosphine Sulfide: a Redetermination at 150K

The structure of this compound was redetermined at 150 K in the search for new polymorphs or phase transitions. Like the analogous triphenylphosphonium methylide, only one polymorph is found at low and room temperature. This is in contrast to the selenium compound, which presents a different form at low temperature.

1,4-Bis(2-amino­benzyl)-1,4-di­aza­cyclo­hexane

The centrosymmetric title compound has the six-membered piperazine ring in the expected chair conformation. There are two intramolecular N-H⋯N hydrogen bonds which give rise to a further two six-membered rings.

Bis(2-hydroxyethyl)(2-nitro­benzyl)ammonium Bromide

This compound exhibits both intramolecular (N-H⋯O) and intermolecular (O-H⋯Br) hydrogen bonding. The latter results in the formation of infinite one-dimensional chains of alternating cations and anions.

(NH₄)₂Na₃(V₃W₃O₁₉).12H₂O

(NH₄)₂Na₃(V₃W₃O₁₉).12H₂O is a mixed V/W salt in which each V/W site has an approximately equal population of V and W atoms. The centrosymmetric polyanion consists of six (V/W)O₆ edge-sharing distorted octahedra sharing a common vertex.

Di­aquacobalt Tetra­cyanonickelate Tetrahydrate

The structure of Co(H₂O)₂Ni(CN)₄.4H₂O consists of alternating metal cyanide sheets and layers of hydrogen-bonded water molecules.

Lithium Hexa­fluoroarsenate Monohydrate, LiAsF₆.H₂O

LiAsF₆.H₂O is isostructural with NaPF₆.H₂O. The structure contains AsF₆ octahedra connected by water molecules via weak F⋯H-O hydrogen bonds.
