| Abstract: | Gomplexation of lanthanides with crown ethers in methanol, ethanol and acetonitrile has been studied by conductometric titration. The molar ratios of lanthanides to crown ethers in the complex compounds,are determined, their stability constants are calculated, and the matching effect, as well as the effects of substituent on the benzene ring of crown ethers anion and solvent on their stability are discussed. |
