Abstract
Crystallization from a ThBr4/DMSO/(Et4N)2Mo3S7Br6 mixture in benzonitrile gave [Th2(µ-SO4)2×(DMSO)12]{[Mo3S7Br5(DMSO)]Br}2·2DMSO·PhCN. The complex has an ionic structure. In the [Th2(µ-SO4)2(DMSO)12]4+ centrosymmetric binuclear cation, the metal atoms are bound by two sulfate bridges and are coordinated by DMSO oxygen atoms, the coordination polyhedron of thorium(IV) being a tricapped trigonal prism (c.n. 9). The [Mo3S7Br5(DMSO)]−cluster anion and the bromide ion form an ion pair with Sax...Br− short contacts, and the DMSO molecule is coordinated to one of the molybdenum atoms via the oxygen atom. The voids of the structure are filled with DMSO and PhCN solvate molecules, the latter being disordered over two positions related by an inversion center.
