چکیده
The title compound, C(16)H(17)N(3)O(2), was synthesized by the reaction of 4-dimethyl-amino-benzaldehyde with 3-hydroxy-benzoic acid hydrazide in methanol. The dihedral angle between the two benzene rings in the mol-ecule is 9.2 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming layers parallel to the bc plane.
