Uranium(IV) iodide, also known asuranium tetraiodide, is aninorganicchemical compound. It is a salt ofuranium inoxidation state +4 and iodine.
Uranium tetraiodide can be prepared from the reaction between uranium and an excess of iodine.[2]
Uranium tetraiodide is a black solid and forms needle-like crystals. Upon heating, it dissociates intouranium triiodide and iodine gas.[2] It crystallizes in the monoclinic crystal system, space group C2/c.[1]
