【 摘 要 】

The title mol­ecular salt, C10H12N3O3S+·C7H3N2O7−, protonation occurs at the amino N atom attached to the benzene ring of sulfamethoxazole. In the anion, there is an intra­molecular O—H⋯O hydrogen bond and the cation is linked to the anion by an N—H⋯O hydrogen bond. In the extended structure, the cations and anions are linked via N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonds, forming a three-dimensional framework.
