Vanadium oxydichloride is the inorganic compound with the formula VOCl2. One of several oxychlorides of vanadium, it is a hygroscopic green solid. It is prepared by comproportionation of vanadium trichloride and vanadium(V) oxides:[1]

V2O5 + VOCl3 + 3 VCl3 → 6 VOCl2

As verified by X-ray crystallography, vanadium oxydichloride adopts a layered structure, featuring octahedral vanadium centers linked by doubly bridging oxide and chloride ligands.[2]
