4-Amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide–2-nitrobenzoic acid (1/1)
In the asymmetric unit of the title co-crystal, C12H14N4O2S·C7H5NO4, the sulfamethazine and 2-nitrobenzoic acid molecules form a heterodimer through intermolecular amide–carboxylic acid N—H...O and carboxylic acid–pyrimidine O—H...N hydrogen-bond pair...
