Vanadium ditelluride is an inorganic compound with the formula VTe2. It is a water-insoluble, gray-black solid. VTe2 has no applications but closely related layered dichalcogenides are subject of much research. [1] VTe2 is the best studied vanadium telluride.

Vanadium ditelluride can be prepared by the reaction of the elements at 1000 °C. [2] The reaction can also be conducted in molten salt. [3] According to X-ray crystallography, it has a layered structure of the cadmium hydroxide packing motif. [2]

A vanadium monotelluride (VTe) is also known (registry number 29888-22-0). It is a nonstoichiometric compound (as is the ditelluride), which crystallizes in the NiAs motif. [4]
