Abstract
In the title compound, C(8)H(8)N(4)O(5), the nitro groups ortho and para to the hydrazone group are twisted by 10.0 (2) and 3.6 (2)°, respectively, relative to the aromatic ring. The structure exhibits an intra-molecular N-H⋯O hydrogen bond between the hydrazide and ortho-nitro groups. There is a strong inter-molecular C=O⋯H-N hydrogen bond, giving rise to chains, and weaker ONO⋯NO(2) [2.944 (2) Å] and C-H⋯O-N inter-actions linking the mol-ecules into a three-dimensional network.Entities:

| 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. |
