3-Chloro-N′-[(2-hydroxynaphthalen-1-yl)methylidene]benzohydrazide

The title compound, C(19)H(15)ClN(2)O(2), was prepared by the reaction of 2-meth-oxy-1-naphthaldehyde with 3-chloro-benzohydrazide in methanol. The dihedral angle between the benzene ring and the naphthyl ring system is 69.0 (3)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the c axis. The crystal packing exhibits π-π inter-actions, as indicated by distances of 3.768 (3) Å between the centroids of the naphthyl rings of neighbouring mol-ecules.
