The title compound, C25H20N4, is a disubstituted methane derivative having two pyridylmethyleneaminophenyl arms, one of which is essentially rigid as all atoms lie on a plane (r.m.s. deviation = 0.074 Å), whereas the other is twisted [dihedral angle between the phenylene and pyridyl rings = 51.1 (4)°]. The angle at the methylene C atom is 113.2 (2)°.
