| Abstract: | N [Bis(2 pyridyl)methyl]pyridine 2 carboxamide was synthesized and characterized. At25 ℃, I =0.1 mol/L KNO3, the stability constants of the binary and ternary systems formed by the ligand with metal ions in ethanol aqueous solution were studied by pH titrations and the appropriate structures with respect to the titration species were proposed according to the literature and the obtained data. Furthermore we also investigated the thermodynamic stability difference between the copper and iron complexes. The results show that a good linear free energy relationship exists in the ternary systems. |
