Ir(acac-O,O)2(acac-C3)(pyridine), 1 is synthesized, and its crystal structure is determined by single crystal X-ray diffraction. In the complex, the central Ir(III) atom displays a distorted octahedral geometry wherein the equatorial positions are occupied by four oxygen atoms of two acetylacetone ligands, and the apical positions are coordinated by a carbon atom of one acetylacetone ligand and a nitrogen atom of pyridine.
