Crystallographic analysis is used to study the structure of (Cd,Pb)Bi2S4 (kudriavite), Bi3In5S12, Pb4In3Bi7S18, Pb1.6In8Bi4S19, Pb4In2Bi4S13, Bi2In4S9 lozenge-like sulfides (with the m plane perpendicular to the translation ~4 Å). It is shown that the structure bases contain regular cation and anion sublattices whose conjugation within the common translation cell is determined by the cation/anion ratio. The independent collective ordering of cations results in complex variants of their occupation of separate crystallographic sites. Sometimes independent anionic ordering leads to unusual coordination environments.
