title: 2,4-Dihydr-oxy-N'-(4-methoxy-benzyl-idene)benzohydrazide.
abstract: The mol-ecule of the title compound, C(15)H(14)N(2)O(4), displays a trans configuration with respect to the hydrazide C=N bond. The dihedral angle between the two benzene rings is 15.0 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯N and O-H⋯O hydrogen bonds, forming layers parallel to the ab plane; an intramolecular N-H⋯O hydrogen bond is also present.
