Abstract: A crystallographic analysis of SrAl₁₂O₁₉ (isostructural to BaFe₁₂O₁₉) and BaFe₁₈O₂₇ showed that the structures of both polytypes contain almost identical cationic and anionic (with participation of a large cation) sublattices, whose geometry is consistent with the high symmetry P6₃/mmc of these compounds. The presence of unified “skeletal” sublattices is considered to be the main condition for the formation of polytype structures.
