Acta Crystallographica Section E: Structure Reports Online is the IUCr’s highly popu- lar open-access structural journal. It provides a simple and easily accessible publication mechanism for the growing number of inorganic, metal-organic and organic crystal struc- ture determinations. The electronic submission, validation, refereeing and publication facilities of the journal ensure very rapid and high-quality publication, whilst key indica- tors and validation reports provide measures of structural reliability. In 2007, the journal published over 5000 structures. The average publication time is less than one month.

The title compound, C9H11N3O4H2O, was prepared by the reaction of dehydroacetic acid and semicarbazide hydro- chloride. 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.
