2,2′-[(2,2′-Bipyridine-3,3′-diyl)bis(nitrilomethylidyne)]diphenol

The title molecule, C24H18N4O2, 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 intramolecular O—H...N hydrogen bond may influence the molecular conformation. In the crystal structure, there are weak π–π stacking interactions with a centroid–centroid distance of 3.7838 (15) Å.
