What is it about?
The uniqueness of the perovskite crystal structure with regard to space - filling of its cation coordination polyhedra is exploited to derive a simple mathematical framework for designing these very common materials.

Why is it important?
Earlier, established approaches to describing perovskite structures - Goldschmidt Tolerance Factor and octahedral tilting / distortion (work of A.M. Glazer) are brought together by calculating V(A)/V(B) volume ratios from experimental crystal data.
