Abstract

The geometry of cation and anion matrices is analyzed in the crystal structures of complex sulfides with the symmetry mirror planes perpendicular to the short translation of ~4 Å. In support of the developed crystalline state concept, the structures exhibit the spatial atomic ordering by the systems of crystallographic planes. This includes the absolute ordering by the symmetry mirror planes that tend to form hexagonal sublattices with trigon 36 nets.
