Two Original Infinite Chains in the New Caesium Tetramolybdate Compound Cs₂Mo₄O₁₃

The structure of Cs₂Mo₄O₁₃ comprises two different types of infinite [Mo₄O₁₃]_n²⁻ chain separated by Cs⁺ ions. The first chain is made from blocks of two MoO₆ octahedra sharing a face while the second chain consists of a set of two MoO₆ octahedra, one MoO₅ square pyramid and one MoO₄ tetrahedron sharing edges and corners.

NbAs₂

The structure of niobium diarsenide has been determined by single-crystal X-ray diffraction. It was found to crystallize with the OsGe₂ structure type.

NaM^IIZr₂F₁₁ (M^II = Mn, Fe, Co, Ni, Zn) Fluorides

The crystal structures of the fluorides NaM^IIZr₂F₁₁ (M^II = Mn, Fe, Co, Ni, Zn) have been refined using single-crystal X-ray diffraction data; these compounds are isostructural with AgPdZr₂F₁₁. Attempts to prepare the analogous Cr^II and Cu^II fluorides failed, probably because these cations would show a strong Jahn-Teller effect.

Zirconium Tungstate

The structure of Zr(WO₄)₂ contains WO₄ tetrahedra each linked by three corners to three ZrO₆ octahedra. The W-O distance to the terminal O atom in each WO₄ tetrahedron is short.

Low-Pressure Polymorph of Co₃Al₂Si₃O₁₂

The structure of cobalt aluminium silicate garnet has been redetermined from diffractometer data. Comparison of the results of the redetermination with those of an earlier study shows that two isostructural pressure-dependent phases exist.

Redetermination of Sodium Cerium(III) Sulfate Monohydrate, NaCe(SO₄)₂.H₂O

The absolute structure of NaCe^III(SO₄)₂.H₂O, which comprises distorted NaO₆ octahedra, distorted CeO₉ tricapped trigonal prisms and slightly irregular tetrahedral sulfate ions, has been determined. The hydrogen bonds in the structure involve only sulfate O atoms as acceptors.

Ta₃S_2−xSe_x, Partial Substitution of Selenium for Sulfur into a Tantalum-Rich Sulfide

Despite some steric crowding among the S atoms in the microporous metal-rich structure of Ta₃S₂, more than 15% Se can be substituted for S without a change of structure type.

Synthetic Magnesium Sodium Hydrogen Monophosphate: MgNa₃H(PO₄)₂

The structure of MgNa₃H(PO₄)₂ contains two-dimensional zigzag sheets of corner-sharing PO₄ tetrahedra and MgO₆ octahedra. The sheets are linked in the third dimension by two types of Na-O polyhedron.

Caesium Lithium Borate: a New Nonlinear Optical Crystal

The structure of the new nonlinear optical borate CsLiB₆O₁₀ has been determined. The borate network consists of B₃O₇ groups and surrounds eight-coordinate Cs and four-coordinate Li atoms.
