Summary

A thermodynamic study of CuII−MII-citrate (MII=NiII, ZnII or CdII) ternary systems has been performed by means of potentiometric measurements of hydrogen ion concentration at different temperatures (10, 25, 35 and 45°C) and at I=0.1 mol dm−3 (KNO3).

The different binary and ternary systems involved have been further characterized by visible spectra and by calculating the spectra (ε versus λ) of all the CuII complexes.

The thermodynamic data suggest strong entropic stabilization for the species under discussion. As regards the visible spectral characteristics of CuII(d-d transitions), the substitution of one CuII ion in the dimer [Cu2(cit)2H−2]4− by NiII or ZnII to form heterobinuclear [CuM(cit)2H−2]4− complexes, gives rise to a change in the visible spectrum.
