1,2-Diphenyl-1H-benzimidazole

Abstract

In the title molecule, C19H14N2, the benzimidazole unit is close to being planar [maximum deviation = 0.0102 (6) Å] and forms dihedral angles of 55.80 (2) and 40.67 (3)° with the adjacent phenyl rings; the dihedral angle between the phenyl rings is 62.37 (3)°. In the crystal, one C—H...N hydrogen bond and three weak C—H...π interactions involving the fused benzene ring and the imidazole ring are observed, leading to a three-dimensional architecture.
