4-Bromo-2-(5-bromo­thio­phen-2-yl)-1-[(5-bromo­thio­phen-2-yl)meth­yl]-5,6-dimethyl-1H-benzimidazole

The title compound, C₁₈H₁₃Br₃N₂S₂, was obtained via the reaction of N-bromo­succinamide with 5,6-dimethyl-2-(thio­phen-2-yl)-1-[(thio­phen-2-yl)meth­yl]-1H-benzimidazole. The compound exhibits rotational disorder of the 5-bromo­thio­phen-2-yl substituent with a refined major:minor occupancy ratio of 0.876 (7):0.124 (7). The 5-bromo­thio­phen-2-yl mean plane is canted to the benzimidazole plane by 20.0 (4) and 21 (4)° in the major and minor components, respectively. In the crystal, weak C—H...N inter­actions link the mol­ecules into infinite C(7) chains along the 2₁ axes.
