Abstract
Abstract The formation of alkali metal cation complexes with 15-crown-5 and benzo-15-crown-5 in ten organic solvents has been investigated by cyclic voltammetry at 25°C. Stability constants of the resulting 1 : 1 complexes have been determined by monitoring the shift in reduction potentials of the cations against ligand concentration. Based on the results obtained the dependences of stabilities of the complexes on Gutmann donicity of the solvents and on standard Gibbs transfer energies of the metal ion from water to a given solvent have been analyzed and discussed.
