title: N'-(5-Chloro-2-hydroxy-benzyl-idene)nicotinohydrazide.
abstract: There are two independent Schiff base mol-ecules in the asymmetric unit of the title compound, C(13)H(10)ClN(3)O(2). The dihedral angles between the benzene and pyridine rings are 12.8 (2) and 1.9 (2)° in the two mol-ecules. Intra-molecular O-H⋯N hydrogen bonds are observed. Mol-ecules are linked into centrosymmetric R(4) (4)(26) motifs by N-H⋯O and N-H⋯N inter-actions.
