Abstract

In both independent molecules of the title compound, C21H17ClN2O, the aromatic rings of the benzyl substituents are located on opposite sides of the benzimidazole ring systems. In one molecule, the rings are aligned at 77.0 (1) and 78.1 (1)° with respect to the fused-ring system, whereas in the other molecule the rings are aligned at 76.0 (1) and 76.9 (1)°. There is an intermolecular Cl⋯O contact of 3.086 (1) Å.
