In the title molecule, C22H18N2O, the seven-membered ring adopts a boat conformation with the planes of the pendant phenyl rings nearly perpendicular to the plane of the aromatic portion of the benzodiazepine core. Pairwise C—H...π(ring) interactions form inversion dimers which pack in zigzag layers associated through weak C—H...O hydrogen bonds.
