In the title complex, [Ir(C11H8N)2(C6H5N2O)], the octahedrally coordinated IrIII atom is bonded to two 2-(pyridin-2-yl)phenyl ligands, through two phenyl C and two pydidine N atoms, and to one pyridine-2-aldoxime ligand through a pyridine N and an oxime N atom. The oxime O atom of the aldoxime unit forms intermolecular C-HO hydrogen bonds, which result in a two-dimensional hydrogen-bonded polymeric network parallel to (100). C-H interactions are also observed.
