It is an orange-coloured solid that degrades in the presence of water.The compound was once prominent as an intermediate in the purification of zirconium metal. ==Structure== Like most binary metal halides, it adopts a polymeric structure. As characterized by X-ray crystallography, the compound exists as a polymer consisting of octahedral Zr(IV) centers, each with a pair of terminal iodide ligands and a four doubly bridging iodide ligands. The Zr-I distances of 2.692 (terminal) and 3.030 Å〔B. Krebs, G. Henkel und M.
