title: 3,3'-Difluoro-4,4'-(p-phenyl-enedi-oxy)dibenzonitrile.
abstract: The title compound, C(20)H(10)F(2)N(2)O(2), was synthesized from hydro-quinone and 3,4-difluoro-benzonitrile. 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.
