In the title compound, C27H18N2, the mean planes of the pendant benzene rings are approximately perpendicular to one another, making a dihedral angle of 79.3 (5)°; the indeno[1,2-b]quinoxaline ring system (r.m.s. deviation = 0.1197 Å) is twisted with respect to the pendant benzene rings by 70.0 (4) and 67.6 (3)°. Weak aromatic π–π stacking [centroid–centroid separation = 3.628 (2) Å] and C—H...π interactions occur in the crystal.
