Abstract
In the title compound, C5H5N3O2, the amino H atom was localized in the vicinity of the endocyclic N atom at a distance of 0.94(2) Angstrom, showing that the compound exists in the form of a zwitterion. Bond len gths and molecular planarity [within 0.048(1) Angstrom] correspond to an overall pi-conjugated system. The molecules are coupled as centrosy mmetric dimers through short N-endo-H ... N-exo hydrogen bonds.
