A new method is proposed for the quantitative description of all perovskite structures, ABX 3. It extends earlier work on the relationship between polyhedral volume ratio VA/VB and octahedral tilt angles [Thomas (1996a). Acta Cryst. B52, 16–31] by

Aurivillius phases are compounds with the general formula (Am−1BmO3m+1)2− (Bi2O2)2+ that consist of (m − 1) perovskite-like units interrupted by bismuth oxide layers. Compounds with A = {Ba2+; Sr2+}, B = {Nb5+}, and m = 2 are studied by EXAFS s
