Aluminium iodide is any chemical compound containing only aluminium and iodine. Invariably the name refers to a compound of the composition AlI3 formed by the reaction of aluminium and iodine or the action of HI on Al metal. The hexahydrate is obtained from a reaction between metallic aluminum or aluminum hydroxide with hydrogen iodide or hydroiodic acid. Like the related chloride and bromide AlI3 is a strong Lewis acid and should be protected from the atmosphere.
