Formation

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]
