چکیده
In the title mol-ecular salt, C(26)H(28)N(4) (2+)·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 inter-actions.
