Cover illustration: Packing diagrams for the two forms of 2,2,3,3,4,4-hexa­fluoro­pentane-1,5-diol, both at 173 K, viewed with respect to the (012) plane and with the [100] axis parallel to the horizontal axis. The hydrogen-bonding network (dashed lines) is preserved through the phase transition. See Ha & Young [Acta Cryst. (2009), C65, o388-o395].

The title cobalt vanadophosphate dihydrate contains flat layers of VO5 and PO4 polyhedra covalently linked by CoII ions coordinated to vanadyl O atoms. This is believed to be the first example of a layered vanadophosphate bridged by a transition metal ion in this manner.

Sr2[Cu(OH)6] crystallizes in the monoclinic system in the space group P21/n (No. 14). The crystal structure is built up from mutually isolated highly elongated Cu(OH)6 octa­hedra and trigonal Sr(OH)6 prisms, forming layers parallel to (110). The Cu(OH)6 octa­hedra are connected into an infinite three-dimensional framework of hydrogen bonds.

The title compound, Na10(Na,Mn)7Mn43(PO4)36, has been synthesized hydro­thermally. Its crystal structure is similar to that of natural fillowite-type phosphates and can be described as a hexa­gonal packing of three types of rods parallel to the c axis, which show an alternation of Mn, Na and P sites and lattice vacancies.

The title compound, tetra­amminedibromidochromium(III) diamminetetra­bromidochromium(III), crystallizes in the space group P\overline{1} (Z = 1). The structure is composed of octa­hedral trans-[CrBr2(NH3)4]+ cations and octa­hedral trans-[CrBr4(NH3)2] anions adopting a distorted CsCl-type lattice.

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.
