2-Hydroxy-N′-(4-hydroxybenzylidene)-3-methylbenzohydrazide

The title compound, C15H14N2O3, was prepared by condensing 4-hydroxybenzaldehyde and 2-hydroxy-3-methylbenzohydrazide in methanol. The two benzene rings make a dihedral angle of 19.03 (11)°. An intramolecular O—H...O hydrogen bond is observed. The crystal structure is stabilized by intermolecular O—H...O and N—H...O hydrogen bonds and C—H...O interactions, which lead to the formation of a three-dimensional network
