摘要：

Potentiometric and calorimetric methods were used to measure the stability constants and thermodynamic values for the complexation of Ag+ with different diaza crown ethers in methanol solvent. The ligands were modified by different substituents at the nitrogen donor atoms. The substituents used have no additional donor atoms. However, for all reactions studied the substituted ligands give higher values of the reaction enthalpies than the unsubstituted ligands. The origin has to be assumed to be due to the differences in the solvation strengths of the ligands.
