  • Abstract

    Reactions of VOCl3 with sodium salts of O,O`-bis(α-naphthyl, β-naphthyl or 2,3,5-trimethylphenyl) dithiophosphate ligands, [{α-C10H7O-, β-C10H7O-, or (CH3)3C6H2O}2PS2Na], in 1:3 molar ratio in toluene yielded new seven coordinated vanadium derivatives of the type [{(RO) 2PS2}3VO] (where R = α-C10H7O-, β-C10H7O- and (CH3) 3C6H2O-). The reactions of [OGOVOCl] (where G = -CH2CH2- or -CH2CH2CH2-), with sodium salts of O,O-bis(α-naphthyl, β-naphthyl or 2,3,5-trimethylphenyl) dithiophosphate ligands, [{α-C10H7O-, β-C10H7O- and (CH3) 3C6H2O}2PS2Na}, in 1:1 molar ratio in toluene were quite facile which afforded 5-coordinated soluble complexes corresponded to formula [OGOVOS2P(OR) 2]. These compounds have been characterized by elemental analysis (C, H, V and S), mass, IR and NMR (1H, 13C and 31P) spectroscopic studies which indicates bidentate linkages of dithiophosphate moieties leading to pentagonal bipyramidal and square pyramidal geometry around the vanadium(V) atom.
