Vanadyl perchlorate can be made by reacting vanadium pentoxide with dichlorine heptoxide at 5°C. It is purified by distillation under a vacuum and recrystallisation at 21°C.[1]

The reaction of barium perchlorate with vanadyl sulfate solution yields a vanadyl perchlorate solution.[2]

A solution of vanadium(V) perchlorate can be made by dissolving vanadium pentoxide in perchloric acid.[3] Pervanadyl perchlorate also known as dioxovanadium perchlorate contains VO2+ ions.[4]


Other perchlorates include vanadyl diperchlorate, oxovanadium perchlorate or vanadium(IV) perchlorate VO(ClO4)2 which dissolves in water.[5][6] Vanadic perchlorate also known as Vanadium(III) perchlorate solution in water is a green-tinged blue colour, significantly different to most other V(III) solutions, which are complexed.[7]
