In the title compound, C(20)H(12)N(2)O(2), the phenyl and benzene rings are mutually perpendicular, with the dihedral angle between the phenyl rings being 87.92 (16)° and those formed between the phenyl rings and the benzene rings being 73.68 (15) and 84.65 (15)°. Helical supra-molecular chains along [010], mediated by C-H⋯N inter-actions, are found in the crystal structure.
