O, the organic and lattice water molecules are linked together
via
N—H⋯O and O—H⋯O hydrogen bonds. A C—H⋯O 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—H⋯O 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)°.
