Abstract: There are two mol­ecules in the asymmetric unit of the title compound, C20H14Br2N2. In the first, the dihedral angles between the mean plane of the benzimidazole group and those of the 4-bromo­benzyl and 4-chloro­phenyl groups are 50.72 (17) and 71.29 (16)°, respectively, while the corresponding angles in the second mol­ecule are 42.09 (16) and 89.05 (17)°. The 4-bromo­benzyl and 4-bromo­phenyl groups make an angle of 68.1 (2) and 85.1 (21)° with each other in the two mol­ecules. In the crystal, weak C-H...N and C-H...Br hydrogen bonds link the mol­ecules along the c-axis direction. Br...Br inter­actions [3.5733 (9)Å] are also observed.
