Cover illustration: The mol­ecular structure of a bis­[ruthenium(II)-porphyrin]-dicarbene complex, showing displacement ellipsoids at the 30% probability level. The 1,2-dichloro­ethane solvent mol­ecules and the p-tolyl groups of the porphyrinate ligands have been omitted for clarity, as have all H atoms and the C atoms of the minor fragment of the disordered ethanol ligand.

BaY2Si3O10 contains zigzag chains of edge-sharing distorted YO6 octa­hedra, linked by horseshoe-shaped trisilicate groups and Ba atoms in irregular eight-coordination.

K4CeZr(PO4)4 has a tunnel structure built of ZrO6 octa­hedra, CeO8 dodeca­hedra and PO4 tetra­hedra. The mixing of Ce and Zr atoms on a single site is associated with disorder of the phosphate groups.

NH4ScF4 represents an addition to the family of layered perovskite-like structures. It is isotypic with phase III of KFeF4, exhibiting a lowering of symmetry due to octahedral tilting.

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.
