Abstract

Dependence of the stability of the silver(I)-18-crown-6 complex on the composition of the binary methanol-DMF solvent was studied potentiometrically. It was found that the increase in DMF content in the binary mixture decreased the stability of the coordination compound. New approach to analysis of the solvation contributions of reagents in the variation of Gibbs energy while substitution of solvent with another one was suggested. It was shown that the shift in the complex formation equilibrium is determined by variation in the solvate state of the central ion.
