    option 2 Ir (CO)Cl (PPh3) is called vaskas complex. Vaska's complex binds O2 reversibly: IrCl(CO)[P(C6H5)3]2 + O2 ⇌ IrCl(CO)[P(C6H5)3]2O2 The dioxygen ligand is bonded to Ir by both oxygen atoms, so-called side-on bonding coordination number of the complex coordination number of the Iridium -6 oxidation state changes from +1 to +3
