Abstract

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.
