The asymmetric unit of the title compound, 2C8H9N2+·C10H6O6S22−, contains a 2-methylbenzimidazolium cation and one half of a naphthalene-1,5-disulfonate anion. The formula unit is generated by an inversion center. In the crystal, N—H
O hydrogen bonds link the components into chains along [001]. In addition, weak C—HO hydrogen bonds and weak C—Hπ interactions are observed. The methyl H atoms were refined as disordered over two sets of sites with equal occupancy.

The r.m.s. deviation from the mean plane for the non-H atoms in the title compound, C7H5BrN2S, is 0.011 Å. In the crystal, the molecules are linked by N—HN and N—HBr hydrogen bonds to generate (010) sheets. Weak aromatic π–π stacking [centroid-to-centroid separation = 3.884 (10) Å] and possible C—HBr interactions are also observed. The crystal studied was found to be an inversion twin.
