title: (E)-3-Hydr-oxy-N'-(2-hydroxy-benzyl-idene)-2-naphthohydrazide.
abstract: The title compound, C(18)H(14)N(2)O(3), is an aroylhydrazone with an approximately planar structure [dihedral angle of 15.27 (13)° between the benzene ring and the naphthyl ring system], stabilized by intra-molecular N-H⋯O and O-H⋯N hydrogen bonds. Inter-molecular O-H⋯O hydrogen bonds with the keto group as acceptor lead to strands along [100]. In terms of graph-set analysis, the descriptor on the unitary level is C(1) (1)(6)S(6)S(6).
