Abstract: In the crystal structure of the title compound, C8H8N4O5·H2O, the organic and lattice water molecules are linked together via N-HO and O-HO hydrogen bonds. A C-HO interaction is also observed between the organic molecules. These hydrogen bonds and interactions lead to the formation of a three-dimensional network. An intramolecular N-HO hydrogen bond also occurs. The dihedral angle between the acetyl group and the almost planar hydrazide moiety [maximum deviation from the least-squares plane is 0.209 (2) Å for one of the nitro O atoms] is 88.5 (3)°.
