Abstract
The new Azo-Schiff ligand type multi dentate have been prepared through two steps. The first one Included the reaction between one equivalent of 4- tert- butyl aniline and one equivalent of salcildihyde to make azo compound. and second step include the reaction of azo with tri ethylene tetra amine in order to make the new Azo-Schiff ligand. The ion metals Cu+2, Zn+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 taken for 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 Copper 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 Cu+2, Zn+2 and Hg+2.
