2-Hydroxy-N′-[(E)-(3-hydroxy-2-naphthyl)methylene]benzohydrazide

In the title molecule, C18H14N2O3, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds influence the molecular conformation; the benzene and naphthalene planes are inclined at a dihedral angle of 11.54 (5)degrees. In the crystal structure, intermolecular O-H center dot center dot center dot O hydrogen bonds link the molecules into chains running in the [01 (1) over bar] direction.
