2-(4-Amino­benzene­sulfonamido)-4,6-dimethyl­pyrimidin-1-ium 2-carb­oxy-4,6-dinitro­phenolate

G. Smith and U. D. Wermuth

Abstract: In the structure of the phenolate salt of the sulfa drug sulfamethazine with 3,5-dinitro­salicylic acid, C12H15N4O2S+·C7H3N2O7-, the dihedral angle between the pyrimidine and benzene rings of the cation is 59.70 (17)°. In the crystal, cation-anion hydrogen-bonding inter­actions involving pyrim­idine-carb­oxy N+-H...O and amine-carb­oxy N-H...O pairs give a cyclic R22(8) motif while secondary N-H...O hydrogen bonds between the aniline group and both sulfone and nitro O-atom acceptors give a two-dimensional structure extending in (001).
