Abstract

The photochemistry of the [IrIIICl6]3- complex in aqueous solutions was studied by the methods of stationary and laser flash photolysis. As the result of a light quantum absorption, parallel processes of photoaquatation and photoionization occur. The aquated electron ea–q, which is formed with a quantum yield of 0.12 (excitation at 266 nm), is predominantly decayed in reactions with the initial complex and dissolved oxygen. The rate constant of ea–q capture by the [IrIIICl6]3- complex was measured. The main final photolysis products are Ir(III) complexes with different compositions of ligands, as well as several percents of Ir(IV) complexes. The formation of final products occurs in the time range from milliseconds to seconds.
