Two virtually superimposable mol­ecules comprise the asymmetric unit of the title compound, C27H27N3. The range of dihedral angles between the central 1,3,5-triazine ring and the attached benzene rings is 20.88 (14)–31.36 (14)°, and the shape of each mol­ecule is of a flattened bowl. The crystal packing features weak C—H⋯π bonds and π–π inter­actions between triazine and benzene rings [centroid–centroid separations = 3.7696 (17) and 3.7800 (18) Å] that result in the formation of supra­molecular layers in the ac plane. The crystal studied was a non-merohedral twin with a minor twin component of 20.7 (3)%.
