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-HN and C-HBr hydrogen bonds link the molecules along the c-axis direction. BrBr interactions [3.5733 (9)Å] are also observed.
