(E)-4-Hydroxy-N′-(2-hydroxy-4-methoxybenzylidene)benzohydrazide

Abstract

In the title compound, C15H14N2O4, the dihedral angle between the benzene rings is 40.59 (4)° and an intramolecular O—H...N hydrogen bond generates an S(6) ring. In the crystal, N—H...O, O—H...O and C—H...O interactions link the molecules into a three-dimensional network.
