2,4-Dihydroxy-N′-(2-hydroxy-4-methoxybenzylidene)benzohydrazide

Abstract

In the title compound, C15H14N2O5, the dihedral angle between the two benzene rings is 4.3 (3)° and the molecule adopts an E configuration with respect to the C=N bond. Intramolecular O—H...N and N—H...O hydrogen bonds are observed. In the crystal structure, the molecules are linked through intermolecular N—H...O and O—H...O hydrogen bonds to form layers parallel to the ac plane.
