Abstract

The title compound, tetrachloro-l~2Cl,2n2Cl-tetrakis - (tetrahydrofuran-O)- 1 n 20,2n 20-di-#-thioxo- 1:2naS-dinio - bium(IV)(Nb--Nb), [Nb2C14S2(CnHsO)4], was obtained by the reaction of NbC14(thO2 (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---CI 2.370(2)- 2.388 (2) and Nb--S 2.324 (2)-2.336 (2) ,4,.
