Abstract
Vanadium chemistry is of interest due its biological relevance and medical applications. In particular, the interactions of high-valent vanadium ions with sulfur-containing biologically important molecules, such as cysteine and glutathione, might be related to the redox conversion of vanadium in ascidians, the function of amavadin (a vanadium-containing anion) and the antidiabetic behaviour of vanadium compounds. A mechanistic understanding of these aspects is important. In an effort to investigate high-valent vanadium-sulfur chemistry, we have synthesized and characterized the non-oxo divanadium(IV) complex salt tetraphenylphosphonium tri-μ-<!?tlsb=-0.11pt>methanolato-κ 6 O:O-bis({tris[2-sulfanidyl-3-(trimethylsilyl)phenyl]phosphane-κ 4 P,S,S',S''}vanadium(IV)) methanol disolvate, (C 24 H 20 P)[V IV 2 (μ-OCH 3 ) 3 (C 27 H 36 PS 3 ) 2 ]·2CH 3 OH. Two V IV metal centres are bridged by three methanolate ligands, giving a C2-symmetric V 2 (μ-OMe) 3 core structure. Each V IV centre adopts a monocapped trigonal antiprismatic geometry, with the P atom situated in the capping position and the three S atoms and three O atoms forming two triangular faces of the trigonal antiprism. The magnetic data indicate a paramagnetic nature of the salt, with an S = 1 spin state.A non-oxo divanadium(IV) complex with bridging methanolate ligands and tris(2-sulfanidylphenyl)phosphane ligands was synthesized and structurally characterized. The magnetic data indicate a paramagnetic nature with an S = 1 spin state.
