Tetrabutylammonium bis[4,4′-dimethyl-2,2′-(3,7-dimethyl-1H-4,2,1-benzothiazasiline-1,1-diyl)dibenzenethiolato]vanadium(III) acetonitrile tetrasolvate

Abstract

In the title compound, [N(C4H9)4][V(C23H21NS3Si)2]·4CH3CN, the VIII atom (site symmetry ) is coordinated by two N,S,S′-tridentate 4,4′-dimethyl-2,2′-(3,7-dimethyl-1H-4,2,1-benzothiaza­siline-1,1-di­yl)dibenzene­thiol­ate ligands in a distorted trans-VN2S4 octa­hedral geometry. The complete cation is generated by crystallographic twofold symmetry, with the V atom lying on the rotation axis. The unusual ligand arose from nucleophilic attack on the coordinated nitrile by the thiol­ate precursor and reduction of nitrile to the imidate.
