Abstract

In the title compound, C20H12N2O2, 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 supra­molecular chains along [010], mediated by C—H⋯N inter­actions, are found in the crystal structure.
