Cover illustration: A packing diagram for 3-bromo­pyridinium tri­bromo­acetate, illustrating the layer structure formed via classical hydrogen bonds, C-H...O interactions and Br...Br contacts (all shown as dashed lines), viewed perpendicular to (102). H atoms not involved in hydrogen bonds have been omitted for clarity. See Jones & Lozano [Acta Cryst. (2004), C60, o876-o878].

In the structure of K2[HCr2AsO10], hydrogen bonds of 2.555 (5) Å between terminal O atoms of shared AsO3OH tetrahedra connect HCr2AsO102− ions. The displacement of the hydrogen-bonded O atoms by 0.586 Å in the predicted transition between phases II and I is larger than that of any other atom.

The title compound was obtained by the reaction of Dy2O3 and B2O3 under conditions of high temperature and pressure (3 GPa and 1323 K) using a Walker-type multi-anvil assembly. Its crystal structure has been determined by single-crystal X-ray diffraction.

A single-crystal synchrotron X-ray study of gadolinium aluminate, GdAlO3, revealed a perovskite-type structure with a common orthorhombic Pnma distortion, which has been discussed in association with the characteristic short Gd—Al—Gd linkage.
