Tris(diethyldithiocarb amato-kappa S) antimony (III), [Sb(C5H10NS2)(3)], is tentatively presumed to comprise a triclinic and a monoclinic polymorph intergrown into each other. The geometry in the triclinic phase is a psi-capped octahedron and that in the monoclinic phase is a psi-pentagonal bipyramid. The study also identifies the polyhedral symbols for a reported pair of polymorphs of another Sb-III coordination compound, as well as for those of published polymorphic modifications of other Bi-III and Pb-II coordination compounds; the symbols in the pair differ in most of these examples. When differentiating related structures of such classes of coordination compounds, lone-pair stereochemistry may be another informative variable, as stereochemical activity is not always apparent from bond distances and angles only.
