Abstract
The title compound, C9H11N3O4·H2O, was prepared by the reaction of dehydroacetic acid and semicarbazide hydrochloride. It crystallizes in a zwitterionic form with cationic iminium and anionic enolate groups. In the crystal structure, the almost planar molecules are held together by N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds, some of them involving the water molecules.
