The peculiarities of LPS of synthesized phases and the known five-slab compounds of the A5BIBII 4 O17 type have been analyzed and the regularities of the distribution of B-type cations in the five-slab perovskite-like structure of compounds and phases of the A5BIBII 4 O17 type have been determined.} }
