Solvation spectra. Part XLIX. The solvation of d10 cations by water and methanol studied by proton magnetic resonance spectroscopy

Abstract

Molal shifts induced in the resonance of hydroxyl protons of water and methanol by the d¹⁰ cations Ag⁺, Zn²⁺, Cd²⁺, and Hg²⁺(methanol only) are systematically down-field of the shifts induced by corresponding alkali and alkaline earth cations. The cause of this effect is through to be primarily an increased covalency in the metal–solvent bonding. Since Zn²⁺ is known to be octahedrally co-ordinated in methanol, a suggestion that the enhanced down-field shift is caused by an asymmetric solvation for Ag⁺ is questioned.
