Double complexes [Co(NH₃)₅(H₂O)]₂[Zr₃F₁₈]·6H₂O and [Co(NH₃)₆]₂[Zr₃F₁₈]·6H₂O

The structures of the title compounds are built from octa­hedral [Co(NH₃)_x(H₂O)_y]³⁺ cations and [Zr₃F₁₈]⁶⁻ anionic chains. O—H⋯F hydrogen bonds help to establish the crystal packing.

A new pillared lithium bis­muth phosphate, LiBi_7.37P₃O₁₉, with elliptical channels

The structure of a new lithium bis­muth phosphate, LiBi_7.37P₃O₁₉, consists of infinite OBi₄ edge-sharing tetra­hedral chains in the ac plane, which form Bi₂O₂ layers parallel to the b axis. They are sandwiched between PO₄ tetra­hedral and Bi polyhedral layers. The PO₄–Bi–PO₄ layers are bridged by columns formed by one Bi polyhedron flanked on each side by LiO₄ tetra­hedra.

Isokite, CaMg(PO₄)F_0.8(OH)_0.2, isomorphous with titanite

Isokite, ideally CaMg(PO₄)F, is isomorphous with C2/c titanite and consists of PO₄, MgO₄F₂, and CaO₆F polyhedra.

Kolbeckite, ScPO₄·2H₂O, isomorphous with metavariscite

This study presents the first structural report of kolbeckite, with the ideal formula ScPO₄·2H₂O (scandium phosphate dihydrate), based on single-crystal X-ray diffraction data. Kolbeckite belongs to the metavariscite mineral group, in which each PO₄ tetra­hedron shares four vertices with four ScO₄(H₂O)₂ octa­hedra and vice versa, forming a three-dimensional network of polyhedra.

Yttrium pyrogermanate, Y₂Ge₂O₇

The structure and absolute configuration of tetra­gonal Y₂Ge₂O₇ was determined from X-ray diffraction data. A comparison is made with related lanthanide pyrogermanates of the series R₂Ge₂O₇ (R = Eu and Tb–Lu).

SrZn₁₁: a new binary compound with the BaCd₁₁ structure

A new Sr–Zn compound with the BaCd₁₁ structure type has been synthesized at high pressure. It contains chains of all-face-capped Zn tetra­hedra which are inter­connected by shared capping atoms.
