      More Details Abstract Fulltext PDF

      Formation of ternary complexes of copper(II) with thiodiglycolic acid as primary ligand(A) and glycine, α-alanine, β-alanine, serine, ethylenediamine or malonic acid as secondary ligand(B) have been investigated in aqueous solution at 30°C employing pH-metric and spectrophotometric methods. The overall formation constants of the mixed-ligand complexes have been evaluated and the relative stabilities of the complexes are compared and discussed in terms of statistical considerations, nature of the donor atoms, steric effects and charge neutralisation as also the distribution of the different complex species present in the solution as a function of pH.
