Syntheses and electronic structures of μ-nitrido bridged pyridine, diimine iridium complexes

The syntheses and X-ray crystal structures of dinuclear mu-azido and mu-nitrido bridged iridium complexes bearing the pyridine, diimine ligand (PDI) are reported. Their electronic structures and formal oxidation states of the metal centers are analyzed by theoretical and experimental methods, revealing the non-innocence of the PDI and nitrido ligands.
