Mechanism of complex formation in methanol: solvent exchange rates for some bivalent metal ions

Abstract

The kinetics of the formation and dissociation of metal(II) chloride complexes in the solvent methanol have been investigated; the rate determining step for the complex formation is shown to be the release of a co-ordinated methanol molecule from the inner co-ordination sphere of the metal ion and the relation between the enthalpy of activation and the entropy of activation for the solvent exchange is shown to be linear.
