Abstract
This thesis works toward the synthesis and characterization using X-ray single crystal of unexpected product of 1-[(1,2,4-triazole-4-yl)imino]diacetyl monoxime (L) as well as elemental analyses, thermal (TG and DTG), spectral (IR, UV-Visible, 13C-NMR, 1H-NMR, mass and EPR), conductivities and magnetic measurements of new metal complexes with different metal ions. 1. Preparation of ligand(L) and its metal complexes: 1-[(1,2,4-triazole-4-yl)imino]diacetyl monoxime(L) was prepared and characterized using X-ray single crystal as well as elemental analyses, thermal (TG and DTG), spectral (IR, UV-Visible, 13C-NMR, 1H-NMR, mass and EPR), thermal gravimetric, conductivities and magnetic measurements of new metal complexes with CuII, FeIII, CoII, NiII, CdII, PtIV and PdII ions. 2. Structural characterization of ligand(L) and its metal complexes: Structural characterization of the (L) has been done by Single X-ray diffraction (SXRD), (FT-IR), also elemental analyses, thermal (TG and DTG), spectral (IR, UV-Visible, 13C-NMR, 1H-NMR, mass and EPR), thermal gravimetric, conductivities and magnetic measurements of its new metal complexes. The proposed chemical formulae of the ligand and its metal complexes are in good agreement with the stoichiometry from their analytical data of carbon, hydrogen, chloride and metal contents. The order (n) and the heat of activation (Ea) of the various decomposition stages are determined from the TG and DrTG using the Coats-Redfern and Horowitz-Metzger methods. 3. Applications of ligand(L) and its metal complexes: Cyclic voltammetry (CV) technique can provide important information about oxidation states of an element in a compound as well as compound̓ ̓s stability in the solvent system in which it is studied. The redox behavior and electron transfer properties of FeIII, CuII, and CoII complexes were investigated by CV. Biological activities as antibacterial, antifungal, antioxidant and the cytotoxic and antitumor activities for ligand and its metal complexes.
