✦ Synopsis

In the title compound, C 14 H 12 N 2 O 3 , the dihedral angle between the two benzene rings is 21.70 ( 4) . An intramolecular O-HÁ Á ÁN hydrogen bond generates an S(6) ring motif. In the crystal structure, the molecules are linked by intermolecular O-HÁ Á ÁO, N-HÁ Á ÁO and C-HÁ Á ÁO hydrogen bonds into a three-dimensional framework.
