N'-(2,4-Dinitrophenyl)acetohydrazide monohydrate

In the crystal structure of the title compound, C8H8N4O5 center dot H2O, the organic and lattice water molecules are linked together via N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds. A C-H center dot center dot center dot 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 center dot center dot center dot 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) angstrom for one of the nitro O atoms] is 88.5 (3)degrees.
