Characteristic
Iridium(III) chloride is the inorganic compound with the formula IrCl3. The anhydrous compound is relatively rare, but the related hydrate is useful for preparing other iridium compounds. The anhydrous salt is a dark green crystalline solid. More commonly encountered is the trihydrate IrCl3(H2O)3.
Chemical formula：IrCl3
Molar mass： 298.58 g/mol (anhydrous)
Appearance： dark green solid hygroscopic
Density： 5.30 g/cm3, solid
Melting point： 763 °C (1,405 °F; 1,036 K) (decomposes)
Solubility in water：insoluble (anhydrous IrCl3), soluble (hydrated derivative)
Magnetic susceptibility (χ)：−14.4·10−6 cm3/mol
Crystal structure：Monoclinic, mS16
Application
Industrially, most iridium complexes are generated from ammonium hexachloroiridate or the related chloroiridic acid (H2IrCl6) as these salts are the most common commercial forms of iridium chlorides.
Hydrated iridium(III) chloride is used in the laboratory for the preparation of other iridium compounds such as Vaska's complex, trans-[IrCl(CO)(PPh3)2]. Alkene complexes such as cyclooctadiene iridium chloride dimer and chlorobis(cyclooctene)iridium dimer can also be prepared by heating the trichloride with the appropriate alkene in water/alcohol mixtures.
