Abstract
Crystallographic analysis of three complex sulfides with the C2/m symmetry (minerals rouxelite Cu2HgPb22Sb28S64(O,S)2, felbertalite Cu2Pb6Bi8S19, and marrucciite Hg3Pb16Sb18S46) established the fact of pseudotranslational ordering of both cations and separately anions by the families of crystallographic planes forming regular cationic and anionic sublattices respectively. One- and two-dimensional fragments of structures close in geometry to the PbS archetype are distinguished, which correlates with the conception of È. Makovicky’s school on the boxwork architecture of sulfosalts.
