G. Smith, U. D. Wermuth and J. M. White

Abstract: The crystal structure of the proton-transfer compound from the reaction of 3,5-dinitrosalicylic acid (DNSA) with sulfanilamide (ABSA), i.e. 4-sulfonamidoanilinium 3,5-dinitrosalicylate, C₆H₉N₂O₂S⁺·C₇H₃N₂O₇^-, shows an extensively hydrogen-bonded polymeric structure in which the protonated amino group of sulfanilamide together with the amide group give a total of eight intermolecular interactions with most of the O atoms of the DNSA anions [NO 2.822 (2)-3.172 (2) Å], together with both of the sulfonate O atoms of adjacent ABSA cations [NO 2.867 (2) and 3.090 (2) Å].
