2-(4-Fluorophenyl)-1-phenyl-1H-benzimidazole

Abstract

In the title molecule, C19H13FN2, the benzimidazole unit is close to planar [maximum deviation = 0.0342 (9) Å] and forms dihedral angles of 58.94 (3) and 51.43 (3)° with the phenyl and fluorobenzene rings, respectively; the dihedral angle between the phenyl and fluorobenzene rings is 60.17 (6)°. In the crystal, three C—H...F hydrogen bonds and two weak C—H...π interactions involving the fused benzene ring lead to a three-dimensional architecture.
