Cover illustration: The proposed mechanism for the transformation of p-phenylenediamine dihydrate into p-phenylenediamine. One set of arrows show the direction of rotation of the C molecules, and the other set indicates pairs of water molecules replaced by the amino groups of the B molecules.

The title structure is occupationally disordered on the La and Pb sites. A large gap was found around the coordination polyhedra, which makes the compound a prospective material in crystal engineering.

The structure of Ba5Cl4(H2O)8(PVO5)8 consists of alternating anionic oxovanadium phosphate (VPO5) and cationic barium chloride hydrate, Ba5Cl4(H2O)8, layers. These layers are linked through Ba—O bonds, generating a three-dimensional framework.

The La3(Zn0.874Mg0.126)11 and Ce3(Zn0.863Mg0.137)11 inter­metallic compounds are isostructural and crystallize in the ortho­rhom­bic La3Al11 structure type. Compared to the structure of La3Al11, in La3(Zn0.874Mg0.126)11, a significant decrease of 11.9% in the unit-cell b axis and and an increase in the other two directions, of 3.6% along a and 5.2% along c, are observed. Such an atypical deformation is caused by the closer packing of atoms in the unit cell due to atom shifts that reflect strengthening of metallic-type bonding.

Ba2Gd2(Si4O13) contains finite Si4O13 chains and Gd2O12 dimers. It is a representative of a rare class of silicates containing Si4O13 chains.

A sample of synthetic (Fe0.81Al0.19)(H2PO4)3 was prepared by hydro­thermal methods in order to determine the crystal structure. The compound is a new monoclinic variety (γ-form) and the structure is based on a two-dimensional framework of distorted corner-sharing MO6 (M = Fe, Al) polyhedra sharing corners with PO4 tetra­hedra.

The crystal structure of dithallium carbonate, Tl2CO3 (C2/m, Z = 4), is stable to 5.82 GPa and does not undergo any phase transitions at lower pressures as reported previously. At higher pressures, the material undergoes a phase transition that destroys the single crystal.

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.
