The title compound, tetrachloro-1κ2Cl,2κ 2Cl-tetrakis-(tetrahydrofuran-Ο)-1κ 2Ο,2κ 2Ο-di-μ-thioxo-1:2κ4S-diniobium(IV)(Nb - Nb), [Nb2Cl4S2(C4H8O) 4], was obtained by the reaction of NbCl4(thf)2 (thf is tetrahydrofuran) with S(SiMe3)2 (hexamethyldisilathiane) in tetrahydrofuran. The compound forms edge-sharing bioctahedral clusters with bridging sulfide ligands and terminal chloride and thf ligands. All thf ligands coordinate in the equatorial plane formed by the Nb - S - Nb - S cycle. Two independent half dimers are found in the asymmetric unit about independent inversion centers located at the midpoints of the Nb - Nb bonds. Distance ranges are: Nb - Nb 2.865 (1)-2.869(1), Nb - Cl 2.370 (2)-2.388 (2) and Nb - S 2.324 (2)-2.336 (2) Å.
