Uranium tetraiodide can be prepared from the reaction between uranium and an excess of iodine.
Uranium tetraiodide is a black solid and forms needle-like crystals. Upon heating, it dissociates into uranium triiodide and iodine gas. It crystallizes in the monoclinic crystal system, space group C2/c.
