Vanadium(II) iodide is the inorganic compound with the formula VI₂. It is a black micaceous solid. It adopts the cadmium iodide structure, featuring octahedral V(II) centers. The hexahydrate [V(H₂O)₆]I₂, an aquo complex, is also known. It forms red-violet crystals. The hexahydrate dehydrates under vacuum to give a red-brown tetrahydrate with the formula V(H₂O)₄I₂.
