The new Azo-Schiff ligand type N2O2 have been prepared through two steps. The first one Included the reaction between one equivalent of 2,3- di methyl aniline and one equivalent of salcildihyde to make azo compound and second step include the reaction of azo compound with tri ethylene tetra amine in order to make the new Azo-Schiff ligand. The ion metals of Ni+2, Pd+2 and Pt+4 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 Mass, 13C-NMR, 1HNMR spectra were taken for the new ligand, Elemental analysis, as well as the molar conductivity and magnetic successptibility for all prepared complexes. These measurements showed that complexes of Nickel and Platenium have octahedral shape. And Square planer for Palladium complex.
