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]
