2-(3,4-Di­fluoro­phen­yl)-1H-benzimidazole

Abstract: In the title mol­ecule, C13H8F2N2, the dihedral angle between the benzimidazole ring system and the di­fluoro-substituted benzene ring is 30.0 (1)°. In the crystal, mol­ecules 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...[pi] inter­action is observed between an H atom of the benzimidazole ring sytem and the [pi] system of the di­fluoro-substituted benzene ring.
