In this study, six new unsymmetrical vic-dioximes, N-(3,4-dimethylphenyl)aminomethylglyoxime (L 1 H 2 ), N-(3-chloro-4-methylphenyl)aminomethyl-glyoxime (L 2 H 2 ), N-(2,6-dimethylphenyl)aminomethylglyoxime (L 3 H 2 ), N-(3,4-dimethylphenyl)aminophenylglyoxime (L 4 H 2 ), N-(3-chloro-4-methylphenyl)-aminophenylglyoxime (L 5 H 2 ) and N-(2,6dimethylphenyl)aminophenylglyoxime (L 6 H 2 ) have been synthesized from chloromethylglyoxime or chlorophenylglyoxime and the corresponding substituted aromatic amines. The Co(II), Ni(II) and Cu(II) complexes of these ligands were prepared. The structures of these new ligands and their complexes are proposed based upon IR, UV-Vis, 1 H NMR spectral data, magnetic measurements, and elemental analyses.

The title compound, C13H11N3O3, crystallized with two independent mol­ecules in the asymmetric unit. One of the mol­ecules is twisted while the other is almost planar, with dihedral angles of 28.02 (6) and 2.42 (9)°, respectively, between the benzene and pyridine rings. Intra­molecular O—H⋯O and O—H⋯N hydrogen bonds are present in both mol­ecules. The two independent mol­ecules are linked by pairs of O—H⋯O hydrogen bonds. The crystal structure is further stabilized by inter­molecular N—H⋯N hydrogen bonds and C—H⋯N and C—H⋯O inter­actions.
