| Abstract: | The complex formation of silver(I) with some sulphur-containing amino acids was studied in aqueous solution by simultaneous pH and pM measurements at 25°C and at an ionic strength of 0.5M (K)NO3. In acid medium complex formation occurs only through the thioether group and the carboxylate group is not involved. In alkaline medium both the thioether and the amino group are bound in either the tetrahedral AgL and AgL2? chelates or the linear dinuclear Ag2L2 species. |
