Cover illustration: Part of the crystal structure of 2,3,10,11-tetra­thia­tricyclo­[,9]hexa­deca-4,6,8,12,14,16-hexa­ene, showing the formation of a [pi]-stacked sheet. For the sake of clarity, H atoms have been omitted. See Yearley, Lippert, Mitchell & Pinkerton [Acta Cryst. (2007), C63, o576-o577].

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.

The structure of a new lithium bis­muth phosphate, LiBi7.37P3O19, 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, ideally CaMg(PO4)F, is isomorphous with C2/c titanite and consists of PO4, MgO4F2, and CaO6F polyhedra.

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.

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).

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.

Special and virtual issues

Acta Crystallographica Section C is planning special issues on

The Structural Chemistry of Homogeneous and Heterogeneous Catalysts

NMR Crystallography.

Full details are available on the special issues page.

The latest virtual issue, featuring Coordination polymers and with an introduction by Len Barbour, was published in July 2014.
