KVTeO₅ and a redetermination of the Na homologue

The MVTeO₅ crystal structure consists of [VTeO₅]_n ribbons linked together by the M⁺ cations located in a distorted bicapped trigonal prism.

Bis­(tri­chloro­phosphine)­iminium salts, [Cl₃P=N=PCl₃]⁺, with transition metal halide counter-ions

Each of the four title structures contains discrete [Cl₃P=N=PCl₃]⁺ cations and metal halide anions. The [NbCl₆] and [TaCl₆] compounds are isostructural.

Cs[Ag₄Zn₂(SCN)₉]

Cs[Ag₄Zn₂(SCN)₉] forms a continuous structure, where the Ag atoms and the thio­cyanate S atoms form chains which run in the ac plane. These chains are bonded together through the Cs and Zn atoms. The structure also contains a disordered thio­cyanate group.

A uranyl sulfate cluster in Na₁₀[(UO₂)(SO₄)₄](SO₄)₂·3H₂O

Na₁₀[(UO₂)(SO₄)₄](SO₄)₂·3H₂O contains an unusual uranyl sulfate cluster that involves a chelating sulfate group in a pentagonal-bipyramidal coordination around the U atom.

Dineodymium tritelluride, Nd₂Te₃

Nd₂Te₃ crystallizes in the U₂S₃ structure type, with each of the two non-equivalent Nd atoms surrounded by seven Te atoms in polyhedra best described as a seven-octahedron and a monocapped trigonal prism.

The superconductor (Tl,Hg,Ca)₂(Ba,Sr)₂(Ca,Sr,Tl)Cu₂O_7.6

The reported 2212-type superconductor provides proof of the chemical flexibility of layered cuprates. The data also reveal a remarkably large apical Cu—Cu distance, due to the presence of Tl and Sr in the intermediate layer.

Hexa­aquacobalt(II) bis­(hypophosphite) and hexa­aquacobalt(II)/nickel(II) bis­(hypophosphite)

The crystal structures of tetragonal [Co(H₂O)₆](H₂PO₂)₂ and [Co_0.5Ni_0.05(H₂O)₆](H₂PO₂)₂ have been determined. The crystals of hexaaquacobalt(II)/nickel(II) bis(hypophosphite) are a solid solution of Co^II and Ni^III hypophosphites. The packing of the Co(Ni) and P atoms is the same as in the structure of CaF₂. The coordination number of six for metal is achieved by water molecules. The hypophosphite anion does not coordinate to the metal cation.

The ordered hydrocerussite-type structure of (PbCO₃)₂·BaF₂

(PbCO₃)₂·BaF₂ crystallizes in the ordered hydro­cerussite-type structure, with a stacking sequence of [c(h)₂]₃ for the close-packed metal atoms.
