Vanadium oxydichloride is the inorganic compound with the formula VOCl<sub>2</sub>. One of several oxychlorides of vanadium, it is a hygroscopic green solid. It is prepared by comproportionation of vanadium trichloride and vanadium(V) oxides:
As verified by X-ray crystallography, vanadium oxydichloride adopts a layered structure, featuring octahedral vanadium centers linked by doubly bridging oxide and chloride ligands.
From VOCl<sub>2</sub>, various blue or green-colored oxotri- and oxotetrachloride salts can be prepared. Examples include N(CH<sub>3</sub>)<sub>4</sub>VOCl<sub>3</sub> and the pyridinium derivative (C<sub>5</sub>H<sub>5</sub>NH)<sub>2</sub>VOCl<sub>4</sub>.
