The crystal structure of anhydrous bis(benzylaminium) 5‐sulfonatosalicylate, 2C 7 H 10 N + ·C 7 H 4 O 6 S 2− , from the reaction of benzylamine with 5‐sulfosalicylic acid, shows the presence of a dianionic 5‐sulfonatosalicylate species, uncommon among proton‐transfer compounds of this acid with organic Lewis bases. Hydrogen‐bonding interactions between both aminium N + —H groups of the two cations and both the sulfonate and carboxylate O‐atom acceptors of the anions give a layered two‐dimensional network structure.
