Uses
Hydrated iridium(III) chloride is used in the laboratory for the preparation of other iridium compounds such as Vaska's complex, trans-. Alkene complexes such as the dimeric {Ir(COD)Cl}2, and {Ir(cycloctene)2Cl}2 can also be prepared by heating the trichloride with the appropriate alkene in water/alcohol mixtures. Industrially, most iridium complexes are generated from H2IrCl6 or (NH4)2IrCl6 as these salts are the most common commercial forms of iridium chlorides, being directly obtained in the purification of iridium.
