In the title compound, C42H30N4, the conformations of the three wings of the molecule are not similar to each other as the torsion angles between the planes of the benzene rings are significantly different. In addition to van der Waals interactions, the crystal structure is stabilized only by intramolecular C-HN hydrogen bonds.
