Abstract: The molecule of the title oxobutanoate derivative, C₁₂H₁₃ClN₂O₃, is nearly planar; the interplanar angle between the benzene ring and the mean plane through the hydrazono-3-oxobutanoate unit is 2.69 (3)°. An intramolecular N-HO hydrogen bond generates an S(6) ring motif. In the crystal packing, C-HO(3-oxo) interactions link molecules into dimers. The dimers thus formed are linked through C-HO(carboxylate C=O) interactions, leading to the formation of ribbons along the [01] direction, which are stabilized via ClCl [3.2916 (3) Å] contacts. The ribbons are stacked via CO contacts [3.2367 (12)-3.3948 (12) Å].
