3,3′-Difluoro-4,4′-(p-phenyl­enedi­oxy)dibenzonitrile

The title compound, C20H10F2N2O2, was synthesized from hydro­quinone and 3,4-difluoro­benzonitrile. The centroid of the central aromatic ring is on a crystallographic center of inversion. The dihedral angle between the central and terminal rings is 77.8 (3)°. In the crystal, chains linked by C—H⋯N bond occur.
