Syntheses and reactions of iridium complexes of octaethylporphyrin

New iridium porphyrin complexes (I-V) have been prepared by the reactions of octaethylporphyrin (OEPH2) or N-methyloctaethylporphyrin (N-Me·OEPH) with μ-dichloro-hexacarbonyl-diiridium(I) ([Ir(CO)3Cl]2) or μ-dichlorobis[π-cyclooctadiene-(1,5)]-diiridium(I) ([Ir(COD)Cl]2). Hydrido- and organo-iridium(III)OEP complexes (VI-XII) have been synthesized by various methods and characterized on the basis of spectroscopic measurements.
