TRIS(TERT-BUTOXO)SILYLTHIOLATO COMPLEXES OF VANADIUM(V, IV, III)

The complexes (t)C4H9N = V(O(t)C4H9)3-n[SSi(O(t)C4H9)3]n, O = V(O(t)C4H9)3-n[SSi(O(t)C4H9)3]n, O = V[SSi(O(t)C4H9)3]2 (9) and VCl[SSi(O(t)C4H9)3]2 have been prepared by reaction of chlorovanadium compounds with LiSSi(O(t)C4H9)3. All complexes are characterized by NMR (H-1, V-51) and ESR spectroscopy. 9 has been found by X-ray diffraction analysis to be a distorted trigonal bipyramidal complex with bidentate thiolate ligands.
