title: 2-Hydr-oxy-N'-[(E)-(3-hydr-oxy-2-naphth-yl)methyl-ene]benzohydrazide.
abstract: In the title mol-ecule, C(18)H(14)N(2)O(3), O-H⋯N and N-H⋯O hydrogen bonds influence the mol-ecular conformation; the benzene and naphthalene planes are inclined at a dihedral angle of 11.54 (5)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains running in the [01] direction.
