Synthesis and some Phoperties of Potassium Oxofluorodiperoxovandate(V)

Abstract

A new solid fluoroperoxo species of vanadium has been synthesised fox the first time, starting from vanadium pentoxide, potassium fluoride and hydrogen peroxide around a pH of 4. The dried solid has the molar ratios of V : O_A : F : K as 1:2:1:2. The IR spectrum shows the presence of the vanadyl group (960 cm⁻¹), the diperoxo group (900 and 880 cm⁻¹) and a vanadyl-fluorine stretching vibration (475 cm⁻¹) in it. The yellow coloured crystalline solid is represented as K₂[V0(0₂)₂F] and named as potassium oxofluorodiperoxovanadate(V).
