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-HN hydrogen bonds are observed. Molecules are linked into centrosymmetric R⁴₄(26) motifs by N-HO and N-HN interactions.
