Zirconium Iodide, ZrI₄

Zirconium Iodide, ZrI₄, was prepared in an impure state by Dennis and Spencer by passing hydrogen iodide gas over zirconium heated to redness; and Stahler and Denk obtained the impure iodide as a rust-coloured sublimate by the same method, the metal or the carbide being employed, and freed it from iodine by shaking it with benzene.

Zirconium iodide is a brown powder which fumes in the air and reacts vigorously with water and alcohol; it combines with ether to form ZrI₄.4(C₂H₅)₂O, and with ammonia to form ZrI₄.8NH₃.
