The molecule of the title compound, C26H26N2O2, has no molecular symmetry (C1). The phenyl rings are asymmetrically twisted by 7.9 (3) and 9.0 (3)° in opposite directions with respect to their attached five-membered ring of the heterocyclic ring system. The heterocyclic ring system is not entirely planar, but is folded in the middle, with a dihedral angle of 176.7 (3)° between the two halves. The molecules are stacked nearly in a `bricks in a brick wall' fashion.
