چکیده
In the title compound, C(14)H(13)N(3)O(3), the dihedral angle between the pyridine and benzene rings is 15.17 (18)°. The torsion angle of the -C=N-N-C- system between two aromatic rings is -167.1 (3)°. Intra-molecular O-H⋯N hydrogen bonding generates S(6) rings. In the crystal structure, neighbouring mol-ecules are linked together along the c axis by weak inter-molecular C-H⋯O and N-H⋯O hydrogen bonds, generating R(1) (2)(6) ring motifs.
