The calculated (model of the ideal layer perovskite-like structure, LPS) and experimental values of ele- mentary cells of AnBnO3n+2-type compounds were analyzed. The interrelations between the peculiarities of LPS deformation of these compounds, the number of layers of BO6 octahedrons in the perovskite-like blocks and the boundaries of morphotropic transitions were established .


Key word AnBnO3n+2 compounds, slab perovskite-like structure.
