T1 - π-stacking and C - X⋯D (X = H, NO2; D = O, π) inter-actions in the crystal network of both C - H⋯N and π-stacked dimers of 1,2-bis-(4-bromo-phenyl)-1H-benzimidazole and 2-(4-bromo-phenyl)-1-(4- nitro-phenyl)-1H-benzimidazole

N2 - Mol-ecules of 1,2-bis-(4-bromo-phenyl)-1H-benzimidazole, C19H12Br2N2, (I), and 2-(4-bromo-phenyl)-1-(4-nitro-phenyl)-1H-benzimidazole, C19H12BrN3O2, (II), are arranged in dimeric units through C - H⋯N and parallel-displaced π-stacking inter-actions favoured by the appropriate disposition of N- and C-bonded phenyl rings with respect to the mean benzimidazole plane. The mol-ecular packing of the dimers of (I) and (II) arises by the concurrence of a diverse set of weak inter-molecular C - X⋯D (X = H, NO2; D = O, π) inter-actions.
