Abstract

In this review of the rod-based sulphosalt structures, the fundamental features of their large- to medium-scale crystal chemistry are described. The principal lozenge-shaped rods represent portions based on the SnS or PbS archetype, their surfaces being alternatively of the pseudotetragonal or pseudohexagonal type. These rods are combined into a structure by means of non-commensurate Q:H interfaces. All of these structures show distinct accumulation of Sb and Bi in rod interiors (representing the lone electron pair micelles) and of Pb (and other large cations) on the pseudotetragonal surfaces of the lozenge-shaped rod. Detailed analysis is given of the largest category of rod-based sulphosalt structures, those based on rods interconnected into layers; 12 different types of such layers have been recognized, based on the mode of interconnection of the rods. Further subdivision in each category reflects the characteristic dimensions of the lozenge-shaped cross-sections. All these derivations result in characteristic geometry and stoichiometry of these structures. A survey is also given of non-layer-like rod- based sulphosalt structures. The classification principles for the three fundamental categories of rod-based sulphosalt structures (layers, chess-board and cyclic types) are established and the more important Pb-Sb, Sn-Sb, Pb-Bi-Sb as well as selected Pb-Bi, Ba-Bi and other sulphosalts are reviewed.
