Vanadium(II) iodide is the inorganic compound with the formula VI<sub>2</sub>. It is a black micaceous solid. It adopts the cadmium iodide structure, featuring octahedral V(II) centers. The hexahydrate [V()<sub>6</sub>]I<sub>2</sub>, 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()<sub>4</sub>I<sub>2</sub>.
The original synthesis of VI<sub>2</sub> involved reaction of the elements.
Solvated vanadium(II) iodides can be prepared by reduction of vanadium(III) chlorides with trimethylsilyl iodide. It reacts with anhydrous ammonia to give the hexaammine complex.
