N′-(2,4-Dinitrophenyl)acetohydrazide
In the title compound, C8H8N4O5, 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 intramolecular N—H⋯O hydrogen bond between the hydrazide and ortho-nitro groups. There is a strong intermolecular C=O⋯H—N hydrogen bond, giving rise to chains, and weaker ONO⋯NO2 [2.944 (2) Å] and C—H⋯O—N interactions linking the molecules into a three-dimensional network
