Abstract

pH-Metric equilibrium investigations were carried out to determine the stability constants, of sixteen copper(II)-diamine-glycine or copper(II)-diamine- diamine mixed ligand complexes. The corresponding enthalpy values were obtained in calorimetric measurements. In every system studied, an increased stability was observed compared to the statiscal case. It was found that, for a given "B" ligand, the formation of the mixed ligand complexes is the more favored, the greater difference between the logK1/K2 values of the parent complexes. The stability increase was explained by the larger enthalpy change in the copper(II)-diamine-diamine complexes, and by the combine effect of the enthalpy and entropy changes in the copper(II)-diamine-glycine systems.
