(E)-N′-[(2-Hy­droxy­naphthalen-1-yl)methyl­idene]-4-methyl­benzohydrazide

In the title compound, C19H16N2O2, the benzene ring and the naphthyl ring system form a dihedral angle of 8.7 (3)° and an intra­molecular O—H⋯N hydrogen bond generates an S(6) ring. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, forming C(4) chains propagating in [001].
