title: 3-Chloro-N'-[(2-hy-droxy-naphthalen-1-yl)methyl-idene]benzohydrazide.
abstract: The title compound, C(18)H(13)ClN(2)O(2), was prepared by the reaction of 2-hy-droxy-1-naphthaldehyde with 3-chloro-benzohydrazide in methanol. An intra-molecular O-H⋯N hydrogen bond influences the mol-ecular conformation; the benzene ring and naphthyl ring system form a dihedral angle of 17.1 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains propagated in [101].
