J.-T. Zhao, J.-J. Qi, Y.-J. Zhou, J.-G. Lv and J. Zhu

Abstract: The asymmetric unit of the title compound, C12H12N2O3, contains two mol­ecules in which the benzene and isoxazole rings are almost coplanar, the dihedral angles between their mean planes being 1.76 (9) and 5.85 (8)°. The two mol­ecules inter­act with each other via N-H...N and N-H...O hydrogen bonds, which link the mol­ecules into layers parallel to the ac plane. The layers stack in a parallel mode with an inter­layer distance of 3.36 (7) Å.
