4,5-Diphen­oxy­benzene-1,2-dicarbo­nitrile

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.
