Iridium tetrachloride is an inorganic compound with the approximate formula IrCl4(H2O)n. It is a water-soluble, hygroscopic amorphous dark brown solid. A well-defined derivative is ammonium hexachloroiridate ((NH4)2IrCl6).[2] It is used to prepare catalysts, such as the Henbest Catalyst for transfer hydrogenation of cyclohexanones.[3]
