title: N'-(2,4-Dinitro-phen-yl)acetohydrazide.
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.
