The title mol-ecule, C(24)H(18)N(4)O(2), lies on a twofold rotation axis with a dihedral angle of 73.7 (1)° between the mean planes of the symmetry-related pyridine rings. The dihedral angle between unique benzene and pyridine rings is 8.0 (1)°. An intra-molecular O-H⋯N hydrogen bond may influence the mol-ecular conformation. In the crystal structure, there are weak π-π stacking inter-actions with a centroid-centroid distance of 3.7838 (15) Å.
