In the title compound, C20H14N4, all the non-H atoms are roughly coplanar with an r.m.s. deviation of 0.0776 Å. In the crystal, molecules are linked by N—H⋯N hydrogen bonds, forming chains along the (). The chains are connected by intermolecular C—H⋯N hydrogen bonds and π–π stacking interactions between inversion-related phenanthroline, imidazole and phenyl rings with centroid–centroid distances in the range 3.777 (1)–3.905 (1) Å.
