Comparative Characteristics of the Nearest Environment Structures of Metal Ions in Water and Acetonitrile (A Review)

The published data of various methods on the structural characteristics of the nearest environment of some monatomic inorganic cations in aqueous solutions and in acetonitrile under standard conditions are summarized. The structures of the first solvation shells of cations in these solvents have been compared quantitatively. It is suggested that for these systems, the structure of solvation shells of cations are independent of the solvent, and is determined only by the physicochemical nature of the ions.
