Ag_3.5Bi_7.5S₁₃, a new member (N = 8) of the homologous series [Bi₂S₃]₂·[AgBiS₂]_(N−1)/2

Silver bismuth sulfide (3.5/7.5/13), Ag_3.5Bi_7.5S₁₃, is the member with N = 8 of the homologous series [Bi₂S₃]₂·[AgBiS₂]_(N−1)/2. All octa­hedral metal positions in its structure show mixed occupancy between Ag and Bi.

RbGa₃(P₃O₁₀)₂: a new gallium phosphate isotypic with RbAl₃(P₃O₁₀)₂

The first rubidium gallium triphosphate has been synthesized by solid-state reaction and studied by single-crystal X-ray diffraction. It crystallizes in the non-centrosymmetric orthorhombic space group C222₁, forming infinite [GaP₆O₂₀]_∞ columns of PO₄ and GaO₄ corner-sharing tetra­hedra along c, linked through the apices with GaO₆ octa­hedra.

The twofold superstructure of titanium(III) oxybromide at T = 17.5 K

TiOBr at 17.5 K has a twofold superstructure of the crystal structure at room temperature, which indicates that TiOBr is in a spin-Peierls state at low temperatures.

Barium chlorite hydrate, Ba(ClO₂)₂·3.5H₂O

The crystal structure of Ba(ClO₂)₂·3.5H₂O has been determined by single-crystal X-ray analysis at 150 K. The structure is layered and contains Ba²⁺ cations surrounded by O atoms in a bicapped square antiprismatic coordination environment.

Two cubic polymorphs of AlGeLi

Lithium aluminium germanium, AlGeLi, crystallizes in two cubic dimorphs. The structure of the F3m form has been confirmed by both powder and single-crystal X-ray diffraction studies. The second dimorph, not previously identified, adopts a disordered centrosymmetric structure with space group Fmm.

A new strontium borophosphate, Sr₆BP₅O₂₀, from synchrotron powder data

Rietveld refinement of a new strontium borophosphate shows that a BO₄ tetra­hedron, of symmetry , is surrounded by an array of four [PO₄]³⁻ tetra­hedra. Sr atoms occupy sites coordinated by eight or nine O atoms.

Li(MoO₂)₂O(AsO₄)

The structure of lithium dioxomolybdenum arsenate oxide, Li(MoO₂)₂O(AsO₄), consists of corner-shared Mo₂AsO₁₂ structural units which form layers. The Mo₂AsO₁₂ units result from the association of corner-shared AsO₄ tetrahedra and Mo₂O₉ groups. The Li⁺ ions are located in the interlayer space.
