Vanadium pentoxide (1 mol) reacts with alkali sulphate (2 mol) or alkali thiocyanate (2 mol) and an excess of hydrogen peroxide at pH 7–8, maintained by the addition of the corresponding alkali hydroxide, to produce yellow oxodiperoxovanadate(V) complexes containing sulphate. The compounds were characterised by elemental analyses, molar conductance measurements, and i.r. and laser Raman spectroscopic studies. The compounds are formulated as M[VO(O2)2] · M2SO4 (M=alkali metal). The peroxide has been shown to be bonded to the vanadium(V) centre in a triangular bidentate (C2v) manner.
