Abstract

In the title complex, [Ir(C17H13N2)2(C5H7O2)], the IrIII atom is hexa­coordinated in a distorted octa­hedral geometry by two C,N-bidentate 2-(5-methyl-3-phenyl­pyrazin-2-yl)phenyl (mdpp) ligands and one O,O-bidentate acetyl­acetonate ligand. The dihedral angles between the phenyl rings and the pyrazine ring are 9.56 (14) and 58.99 (14)° for one mdpp ligand and 9.34 (14) and 79.94 (15)° for the other.
