چکیده
The mol-ecule of the title compound, C(12)H(11)N(3)O(2), is approximately planar with an r.m.s. deviation of 0.0814 Å from the plane through all the non-H atoms. The dihedral angle formed by the benzene and isoxazole rings is 6.88 (16)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond, forming an S(6) ring, and the mol-ecule displays an E configuration with respect to the C=N double bond. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds form centrosymmetric dimers which are further linked by weak C-H⋯N inter-actions augmented by very weak C-H⋯π contacts, forming layers parallel to (120).
