摘要

Abstract The stability constants of complexes of 12-, 15-, and 18-membered diaza crown ethers, N, N′-dimethyl diaza crown ethers, and N, N′-bis (2-hydroxyethyl) diaza crown ethers with alkali and alkaline-earth metal ions in 95% aqueous methanol at 25° C were determined. The stability of the complexes of unsubstituted diaza crown ethers with alkali metal cations is low, probably because of stabilization of the exo, exo conformation of the ...
