The mol­ecule of the title compound, C20H16N2O2, is centrosymmetric, the inversion center being located at the mid-point of the central azine bond. The conformation around the C=N bond is E. The whole mol­ecule (except for the H atoms) is essentially planar, with an r.m.s. deviation of 0.07 Å. In the crystal, mol­ecules are linked head-to-tail by pairs of C—H⋯O hydrogen bonds, forming inversion dimers, and resulting in the formation of chains propagating along [011].
