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]
