Isolation, characterization and photophysical properties of a 2-(4,6-difluorophenyl)pyridyl Iridium(III) methoxide dimeric complex

A novel iridium(III) alkoxide dimeric complex containing 2-(4,6-difluorophenyl)pyridyl cyclometalating ligand was synthesized and characterized by IR, 1H-NMR and X-ray crystallographic methods. Aside from its novel structure and mechanistic implications as intermediate during the formation of homoleptic or heteroleptic Ir(III) complexes, it is interesting to note that this complex shows significant photoluminescence.
