Complex-formation equilibria of silver(I) ions and aza-crown ethers and aliphatic amines were studied in acetonitrile, propylene carbonate, and methanol by the potentiometric method. It was found that AgL+ and AgL2 + species (L denoting the organic ligand) are formed. The stability constants of the complexes with crown ethers are greater compared to those with amines. It was found that solvent composition and cavity size of macrocyclic polyethers influence significantly the stability constants of the complexes formed. The difference in stability constants for various crown polyethers is discussed in terms of possible structure of the complexes.
