Abstract

In the title mol-ecule, C13H8F2N2, the dihedral angle between the benzimidazole ring system and the di-fluoro-substituted benzene ring is 30.0 (1)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, forming chains along [010]. In addition, weak C-H⋯F hydrogen bonds connect chains into a two-dimensional network parallel to (001). A weak C-H⋯π inter-action is observed between an H atom of the benzimidazole ring sytem and the π system of the di-fluoro-substituted benzene ring.
