Vanadyl perchlorate
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; it ignites organic solvents on contact and explodes at temperatures above 80 °C.
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.A solution of vanadium perchlorate can be made by dissolving vanadium pentoxide in perchloric acid.
The reaction of vanadium pentoxide and dichlorine hexoxide could produce VO3:
