In the title mol-ecule, C(24)H(18)N(4)O(2), the dihedral angles between the mean plane of the phenanthroline ring system and the pyridine rings are 82.52 (5) and 71.58 (4)°. The dihedral angle between the two pyridine ring planes is 53.54 (6)°. In the crystal structure, there are π-π stacking inter-actions between 1,10-phenanthroline rings, with centroid-centroid distances of 3.6101 (11) and 3.5864 (11) Å.
