2-Hydr-oxy-N'-(2-methoxy-naphthyl-idene)benzohydrazide.

The title Schiff base compound, C(19)H(16)N(2)O(3), prepared by the reaction of 2-meth-oxy-1-naphthyl-aldehyde and 2-hydroxy-benzohydrazide, crystallizes with two independent mol-ecules in the asymmetric unit. Each mol-ecule exists in a trans configuration with respect to the methyl-idene group. The naphthyl ring system make dihedral angles of 65.0†(2)° and 55.8†(2)° with the planes of the benzene rings. Intra-molecular N-H⋯O and O-H⋯O hydrogen bonds help to stabilize the mol-ecular conformations. In the crystal structure, mol-ecules are linked into one-dimensional chains parallel to the c axis by inter-molecular O-H⋯N and O-H⋯O hydrogen bonds.
