Reactions of vanadium(V) oxide tribromide: preparation and properties of vanadium(IV) oxide dibromide complexes

Abstract

The reactions of VOBr₃ with a variety of ligands are reported. The following complexes have been prepared, and their structure studied: VOBr₂(L–L)(where L–L = 1,2-dimethoxyethane or 2,2′-bipyridyl). VOBr₂L₂, (where L = tetrahydrofuran, 1,4-dioxan, hexamethylphosphoramide, pyridine, quinoline, triphenylphosphine, 1,4-thioxan, and tetrahydrothiophen), VOBr₂L₃(where L = diphenyl sulphoxide or pyridine), and VOBr₂L₅(where L = dimethyl sulphoxide).
