N2  - The rated (a model of ideal layer perovskite-like structures) and experimental values of the periods of elementary cells of five-layer phases CaLn4?xLnI xTi5O17, SrLn4-xLnI xTi5O17, Ln5-xLnI xTi4FeO17 (Ln=La, Pr, Nd, LnI=Pr, Nd, Sm, Gd, Dy, Yb) are analyzed. The interrelations between the peculiarities of a deformation of their crystal structure and the boundaries of morphotropic transitions of five-layer compounds and phases of the A5B5O17 type are established.
