(E)-6-Chloro-N'-(3,5-dichloro-2-hydroxybenzylidene)nicotinohydrazide

Abstract: The title Schiff base compound, C₁₃H₈Cl₃N₃O₂, was synthesized by the condensation reaction of 3,5-dichlorosalicylaldehyde with 6-chloronicotinic acid hydrazide in 95% ethanol. The molecule is nearly planar, with a dihedral angle of 1.9 (2)° between the aromatic ring planes, and an intramolecular O-HN hydrogen bond is observed. In the crystal, the molecules are connected by intermolecular N-HO hydrogen bonds into infinite chains propagating in [100].
