3,3′-[1,2-Phenyl­enebis(methyl­ene)]bis­(1-ethyl­benzimidazolium) dibromide

In the title mol­ecular salt, C₂₆H₂₈N₄²⁺·2Br⁻, the central benzene ring makes dihedral angles of 76.75 (11) and 82.40 (10)° with the pendant benzimidazole rings. The corresponding angle between the benzimidazole rings is 57.03 (9)°. In the crystal, the cations and anions are linked via C—H...Br hydrogen bonds, forming sheets lying parallel to the bc plane. The crystal structure also features weak C—H...π inter­actions.
