| Summary: | Five transition metal complexes (3-7) of 2-benzoylpyridine-2-hydroxybenzhydrazone ligand
(1) and another two transition metal complexes (8-9) of N.N' -bis(2-thiophene carboxaldebyde)-1,2-ethylenediamine ligand (2) have been synthesized. Schiff base ligands (1-2) and their transition metal complexes (3-9) were characterized by using CHN analysis, UV-Visible and IR spectral studies. Among them, ligand (1) and its complex (7) have also been analysed by 'H NMR analysis. All transition metal complexes (3-9) are non electrolytic in nature. Spectral studies suggested that ligand (1) acts as a mononegative tridentate nature, while the ligand (2) acts as a neutral tetradentate nature in their transition metal complexes. The probable structrures of the complexes have been deduced on the basis of their analytical and spectroscopic data. |
