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]
