Rb(GaPO4)2(OH)(H2O)·H2O exhibits a three-dimensional framework with intersecting eight-ring channels, in which the alkali cations and the water mol­ecule are encapsulated. This network belongs to the leucophosphite structural type.

The title compounds are isotypic. KMo5O13 has a three-dimensional tunnel built by the corner-sharing of MoO6 octahedra; K+ cations are located in the tunnels. In KNb1.76Sb3.24O13, the Nb and Sb atoms occupy the same sites.

Fe7(PO4)2(HPO4)4 is isostructural with Mn7(PO4)2(HPO4)4 and Co7(PO4)2(HPO4)4. The structure is based on a framework of edge- and corner-sharing FeO6, Fe5 and PO4 polyhedra, isotypic with that found in the mixed-valence iron phosphate Fe7(PO4)6. The Fe atoms are purely in the divalent state, just like the Co atoms in Co7(PO4)2(HPO4)4, the necessary charge balance being maintained by the addition of H atoms in the form of bridging Fe—OH—P groups.

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.
