| Abstract | ||
| The macrocycle ligand type N2S2 have been prepared through two steps.the first Included the reaction between two equivalent of mercapto acetic acid and one eq- Univalent of 1,4-phenylene di amine , the second included the reaction of first step precursor with penta erythritol tetra bromide,to obtainted the target ligand .the Co+2 with metal from there action of the ligand Complexes were prepared Ni+2 , Cu+2 ions 1:2 ratio , the prepousd compounds were characterized by FT-IR , UV-Vis , NMR , C.H.N spectoscopies , mass spectra as well as the molar conductivity and magnetic successptibility, stability constant and mole ratio was corried out of prepared complexes these measurements shows the suggested geometry around the cobalt ion is distorted octahydral and squar planer around nickel ion and tetrahydral around cupper ion . The effect of temperature on the stability constants were found to raising the Temperature .the thermodynamic function (ΔG, ΔH , ΔS) of the formed complexes were calculated at range of temperature that showed complexes reaction was undo thermic and spontaneous .formation | ||
