Complexes [Cp*Ir(ppy)NO3] (ppy = 2-phenylpyridine, 1), [Cp*Ir(2′,4′-F2-ppy)NO3] (2b), [Cp*Ir(κ2-C2,C2′-NHC)Cl], (κ2-C2,C2′-NHC = κ2-C2,C2′-1,3-bis(4-(N,N-dimethylamino)phenyl)-imidazol-2-ylidene, 3), [Cp*Ir(bpyr)(SOMe2)] (bpyr = bis-diethyl-pyrrole, 4), [Cp*Ir(bimH2)Cl]Cl (bimH2 = 2,2′-bisimidazole, 5) and [Cp*IrCl(μ2-κ2-κ1-bimH)IrCl2Cp*] (6) have been synthesized and characterized in solution by multinuclear and multidimensional NMR spectroscopy. The structures in the solid state of 3 and 6 have been determined by means of single-crystal diffraction X-Ray studies. Complexes 1–6 were found to be effective catalysts for water oxidation to molecular oxygen driven by cerium ammonium nitrate. The highest activity was observed for 4 (TOFmax = 12 min−1, TON > 500), 5 (TOFmax = 23 min−1, TON > 500) and 6 (TOFmax = 51 min−1, TON > 500) bearing more electron-donating ligands.
