Synthesis, Characterization and Biological Study of New Azo -Schiff Ligand type N2O2 and It's Divalent Metal Ion Complexes with Zinc, Cadmium and Mercury

Abstract

       The new Azo-Schiff  ligand type N₂O₂ have been prepared through two steps. The first one Included the reaction between one equivalent of P-Phenoxy aniline and one equivalent of Salcyldehyde salcildihyde to prepare  azo compound .and second step include the reaction of azo compound   with tri ethylene tetra amine in order to prepare  the new Azo-Schiff ligand. The ions metal of  Zn⁺², Cd⁺²  and Hg⁺² with the new azo-Schiff ligand Complexes were prepared with mole ratio (1:1) (M: L) the prepared compounds were characterized by FT-IR, UV-Vis, while ¹HNMR spectra were takenor the new ligand and it complex with mercury, Elemental analysis, as well as the molar conductivity and magnetic successptibility for all prepared complexes. These measurements showed that complexes of Cadmium and Zinc have octahedral shape, and tetrahedral for Mercury complex. The biological activity was evaluated against two kinds of bacteria, gram positive and gram negative for the new Azo-Schiff  ligand and it's complexes with  Zn⁺² , Cd⁺²  and Hg⁺² .
