Abstract

On the basis of the analysis and the generalization of data on the synthesized by the authors and known (MeII, Ln)n+1BnO3n+1-type compounds with layered perovskite-like structure (LPS), the necessary conditions of existence of compounds and phases compositions (MeII, Ln)n+1BIIInO3n+1 and (MeII, Ln)n+1(BIII,BIV)nO3n+1 (n = 1 and 2) with LPS are determined. They account for the ratio of the size of atoms and the ionicity of bonds A — O and B — O in crystals and substantially simplify the directed search for new layered perovskite-like compounds and (MeII, Ln)n+1BnO3n+1-type phases.
