Cover illustration: A view of the molecule of dichloro(isopropylamido)bis(iso­propylamine)(isopropylimido)­tantalum(V), with ellipsoids drawn at the 30% probability level. Methyl-H atoms have been omitted for clarity and only one of the two possible orientations of the disordered iso­propyl groups is shown. See Burland, Meyer & Geib [Acta Cryst. (2003), C59, m46-m48].

Two members of the solid-solution series Ba1−xAl2−2xSi2+2xO8, with x = 0.20 or 0.06, have been synthesized and are shown to have the celsian structure, but with Ba deficiency.

The crystal structure of LaTiO3.41 consists of (110) perovskite-type slabs with a width of five TiO6 octahedra, which are separated by additional oxy­gen layers. A superstructure is observed in the [100] direction.
