2-Aminoanilinium benzene-1,2-diaminium tris(4-methylbenzene-1-sulfonate)

In the title molecular salt, C6H10N22+·C6H9N2+·3C7H7O3S−, one of the cations is doubly protonated and one is singly protonated with charge balance achieved by three sulfonate anions. The crystal packing features N—H...O and C—H...O hydrogen bonds. The ions are arranged into a two-dimensional network along the (010) plane and the structure is further consolidated by weak C—H...π interactions.
