Abstract
The crystal structure of the proton-transfer compound from the reaction of 3,5-dinitrosalicylic acid (DNSA) with sulfanilamide (ABSA), i.e. 4-sulfonam idoanilinium 3,5-dinitrosalicylate, C6H9N2O2S+.C7H3N2O7-, shows an extensiv ely hydrogen-bonded polymeric structure in which the protonated amino group of sulfanilamide together with the amide group give a total of eight inter molecular interactions with most of the O atoms of the DNSA anions [N . . . O 2.822 (2)-3.172 (2) Angstrom], together with both of the sulfonate O atom s of adjacent ABSA cations [N . . .O 2.867 (2) and 3.090 (2) Angstrom].
