Abstract
The title compound, {[Pr(C2H6OS)8]2[Mo6Ag6S24]}n, contains polymeric Mo6S24Ag6 2− anions and [Pr(Me2SO)8]3+ cations, forming a one-dimensional polymeric Mo/S/Ag cluster. The anion assumes the conformation of a zigzag chain. The trivalent cations are arrayed amongst the anionic chains and are well separated from each other. Each Mo and Ag atom is coordinated by four S atoms in a distorted tetrahedral geometry. The Pr3+ atom is coordinated by eight dimethyl sulfoxide ligands, forming a polyhedron-shaped distorted square antiprism.
