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]
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]
