In the 8H8N4O5·H2O, 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)°.

An aqueous solution (10 ml) containing of 2,4-dinitro-phenylhydrazine (2 mmol) was added to pure acetic acid (10 ml). The obtained solution was stirred at 333 K for 30 min and then left to stand at room temperature. Yellow single crystals of the title compound were obtained after some days.
H atoms were treated as riding, with C—H = 0.93 and 0.96 A° for phenyl and methyl H-atoms, respectively. The H-atoms bonded to O and N were located from difference maps and were allowed to refine freely. The Uiso(H) were allowed at 1.5Ueq(C methyl) or 1.2Ueq(C phenyl).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Hydrazine and its derivatives have been intensively investigated due to their attractive pharmacological applications (Zahid & Sherazi, 1997). In addition, hydrazones exhibit physiological activities in the treatment of several diseases such as tuberculosis (Monfared et al., 2007). We report here the synthesis and the crystal structure of the title compound.
The bond distances and angles in the title compound (Fig. 1) agree very well with the corresponding bond distances and angles reported in a closely related compound (Okabe, et al., 1993). There is a strong intramolecular N—H···O hydrogen bond that stabilizes the molecular structure of the title compound. In the crystal structure, pairs of symmetry-related molecules are connected into centrosymmetric clusters via medium O—H···O and N—H···O hydrogen bonds forming twenty-six-membered rings with an R66 (26) motif (Bernstein, et al., 1995). The water molecule is surrounded by three organic groups through hydrogen bonds type O—H···O and N—H···O. The crystal packing (Fig. 2) is stabilized by these intermolecular hydrogen bonds and C—H···O interactions (Table 1) resulting in a three dimensional network.
