5-Methyl-N'-(3-nitrobenzylidene)isoxazole-4-carbohydrazide.

The mol-ecule of the title compound, C(12)H(10)N(4)O(4), displays an E configuration about the C=N bond. The dihedral angle between the benzene and isoxazole rings is 1.36 (5)° and the mol-ecular conformation is stabilized by the an intra-molecular C-H⋯N hydrogen bond. In the crystal structure, centrosymmetrically related mol-ecules are connected by pairs of N-H⋯O hydrogen bonds into dimers, which are further linked into a three-dimensional network by inter-molecular C-H⋯O hydrogen bonds and by π⋯π stacking inter-actions involving adjacent benzene and isoxazole rings, with a centroid-centroid separation of 3.861 (3) Å.
