title: 3,3'-[1,2-Phenyl-enebis(methyl-ene)]bis-(1-heptyl-benzimidazolium) dibromide monohydrate.
abstract: In the title salt, C(36)H(48)N(4) (2+)·2Br(-)·H(2)O, the central benzene ring makes dihedral angles of 84.77 (9) and 69.92 (7)° with the adjacent imidazole rings. In the crystal, one of the heptyl groups is disordered over two sets of sites with an occupancy ratio of 0.474 (5):0.526 (5). In the crystal, the cations, anions and water mol-ecules are connected via inter-molecular O-H⋯Br, C-H⋯Br and C-H⋯O hydrogen bonds, forming a three-dimensional network.
