6-Chloro-N′-(2-hydroxy-1-naphthylmethylene)nicotinohydrazide
نویسنده
چکیده
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 hydrogen bond. The crystal structure is stabilized by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming chains running along the b axis.
