title: 2,4-Dihydr-oxy-N'-(2-hydr-oxy-4-methoxy-benzyl-idene)benzohydrazide.
abstract: In the title compound, C(15)H(14)N(2)O(5), the dihedral angle between the two benzene rings is 4.3 (3)° and the mol-ecule adopts an E configuration with respect to the C=N bond. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds are observed. In the crystal structure, the mol-ecules are linked through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds to form layers parallel to the ac plane.
