Iridium (IV) chloride is an inorganic salt from the group of chlorides with iridium as the cation .
Extraction and presentation
Iridium (IV) chloride can be obtained by reacting ammonium hexachloroiridate with chlorine or aqua regia . The products shown mostly contain iridium (III) chloride or hydrogen chloride as an admixture, which is why the existence of the compound is not considered certain by some literature.
properties
Iridium (IV) chloride, as a hydrate, is a black solid that is soluble in water. The anhydrate is a brown, hygroscopic amorphous solid that is soluble in water and ethanol.
use
Iridium (IV) chloride is used in chemical analysis to test for nitric acid , in microscopy and in electroplating solutions . It acts as a catalyst precursor for the stereoselective reduction of cyclohexanones .
