The title compound, C22H15N3O2, can be described as a ketone with a phenol substituent and a terpyridine ligand coordinated to the carbonyl group. The three six-membered rings of the terpyridine ligand are not coplanar. The dihedral angles between the mean planes of the central ring and the external pyridine ligands are 22.77 (9) and 26.77 (7)°. The central ring of the terpyridine ligand is also not coplanar with the o-hydroxy phenyl ring, the dihedral angle being 39.72 (5)°. An intramolecular O—H...O hydrogen bond occurs. The crystal structure of the title compound is consolidated by C—H...O and C—H...N hydrogen bonding interactions.
