Synthesis, spectral characterization and cytotoxic activity of 3D-transition metal complexes with O-vanillin benzoylhydrazone ligand
Six new Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) complexes (2-7) of o-vanillin benzoylhydrazone ligand (1) have been synthesized and characterized. The ligand (1) and its 3dmetal complexes (2-7) were characterized by elemental analysis, molar conductivity, UVVisible, FT-IR and 1H NMR spe...

| Summary: | Six new Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) complexes (2-7) of o-vanillin
benzoylhydrazone ligand (1) have been synthesized and characterized. The ligand (1) and its 3dmetal
complexes (2-7) were characterized by elemental analysis, molar conductivity, UVVisible,
FT-IR and 1H NMR spectroscopic studies. The spectroscopic data of the complexes (2-
7) suggested that the ligand (1) is acted as a dinegative tridentate chelating system and is
coordinated to central metal(II) atom through phenoxide-O, atomethine-N and carboxylate-O
atoms. Four coordinated molecular structure has been proposed for the synthesized 3d-transition
metal complexes. The ligand (1) and its metal complexes (2-7) have also been tested for their
cytotoxicity and found to be less active against Artemia salina. |
