Molecules of 1,2‐bis(4‐bromophenyl)‐1 H ‐benzimidazole, C 19 H 12 Br 2 N 2 , (I), and 2‐(4‐bromophenyl)‐1‐(4‐nitrophenyl)‐1 H ‐benzimidazole, C 19 H 12 BrN 3 O 2 , (II), are arranged in dimeric units through C—H...N and parallel‐displaced π‐stacking interactions favoured by the appropriate disposition of N‐ and C‐bonded phenyl rings with respect to the mean benzimidazole plane. The molecular packing of the dimers of (I) and (II) arises by the concurrence of a diverse set of weak intermolecular C— X ... D ( X = H, NO 2 ; D = O, π) interactions.
