Synthesis of a new ligand and its complexes formed by the reaction of 4-isonitrosochloroacetophenone with 2-aminopyridine

In this study, a bidentate oxime derivative ligand, which is not available in the literature, was obtained by using 4-isonitrosochloroacetophenone. Two new complexes were synthesized by adding Ni(II) and Cu(II) metal salts to these ligands. The synthesized ligand and complexes were characterized by 13C-NMR, 1H-NMR, FT-IR, LC-MS and TG-DTA. Experimental data were found to be in good agreement with the theoretical data. In addition, ab-initio calculations of ligand based on Density Functional Theory (DFT) and molecular properties were elucidated using the 6-31G(d,p) base set. Vibration mode periods are determined on the basis of potential energy distribution (PED). When the experimental structure parameters were compared with the theoretical data, it was determined that they were compatible. KEYWORDS: Oxime, Copper complexes, Homonuclear complex
