The title compound, C(17)H(12)ClN(3)O(2), was synthesized by the Schiff base condensation reaction of 2-hydr-oxy-1-naphthaldehyde with 6-chloro-nicotinic acid hydrazide in a methanol solution. The mol-ecule displays a trans configuration with respect to the C=N and C-N bonds. The dihedral angle between the naphthyl ring system and the pyridine ring is 7.6 (4)°. There is an intra-molecular O-H⋯N...

The title compound, C(18)H(13)BrN(2)O(2), was synthesized by the reaction of 2-hydr-oxy-1-naphthaldehyde with 4-bromo-benzohydrazide. This Schiff base mol-ecule has an E configuration about the C=N bond and is almost planar, the dihedral angle between the mean planes through the substituted benzene ring and the naphthyl system being 6.6 (2)°. There is an intra-molecular O-H⋯N hydrogen bond invo...
