Abstract: | CAS-PAN analysis for revealing close-packed cristallographic planes is performed to investigate the structures of a series
of binary chalcogenides containing heavy cations and having D

, symmetry with a short spacing perpendicular to the mirror plane. For chalcogenides with complex compositions, complex relationships
between planes are typically observed. Absolute ordering of atoms by mirror planes generally coexists with ordering along
the other two directions. By analogy with simple sulfides, these structures have cationic and anionic matrices of AA′ type,
that is, one-layer hexagonal packing of trigon nets with a base plane split into two planes and with a doubled number of sites
with respect to the number of atoms.
