Vanadyl perchlorate or vanadyl triperchlorate is a golden yellow coloured liquid or crystalline compound of vanadium, oxygen and perchlorate group. The substance consists of molecules covalently bound and is quite volatile.
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.
The reaction of barium perchlorate with vanadyl sulfate solution yields a vanadyl perchlorate solution.
A solution of vanadium(V) perchlorate can be made by dissolving vanadium pentoxide in perchloric acid. Pervanadyl perchlorate also known as dioxovanadium perchlorate contains VO2+ ions.
Other perchlorates include vanadyl diperchlorate, oxovanadium perchlorate or vanadium(IV) perchlorate VO(ClO4)2 which dissolves in water. 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.
