N'-(5-Chloro-2-hydroxybenzylidene)nicotinohydrazide

C.-G. Ren

Abstract: There are two independent Schiff base molecules in the asymmetric unit of the title compound, C13H10ClN3O2. The dihedral angles between the benzene and pyridine rings are 12.8 (2) and 1.9 (2)° in the two molecules. Intramolecular O-H...N hydrogen bonds are observed. Molecules are linked into centrosymmetric R44(26) motifs by N-H...O and N-H...N interactions.
