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]

From VOCl2, various blue or green-colored oxotri- and oxotetrachloride salts can be prepared. Examples include N(CH3)4VOCl3 and the pyridinium derivative (C5H5NH)2VOCl4.[3]
