Abstract
A conductance study of the interaction between Fe(ClO4)3, Cu(ClO4)2, Fe(NO3)3, Cu(NO3)2, Hg(NO3)2 and Cd(NO3)2 with phenyl-aza-15-crown-5 (PhA15C5) in different acetonitrile-water mixtures has been carried out at various temperatures. The formation constants were determined at various temperatures. It was found that the stability of the nitrate salts decreases in the order Hg2+ > Cu2+ > Fe3+ > Cd2+ and the formation constants decrease as the percentage of acetonitrile decreases in the mixture. The counter anion also affects the stability of the complexes, where the metal perchlorate-crown complexes are more stable than those of the metal nitrate salts. The enthalpy and entropy of the complexation were calculated and were found to be sensitive to solvent composition.
