Abstract
Published data derived from measurements of nuclear magnetic resonance line broadening for the M(ll) perchlorates in polar solvents were used in a comparison of viewpoints for the role of the solvent in the solvent exchange reactions by the solvated octahedral metal ions. Two interpretations which were considered are: (a) correlations of enthalpy-based measures of solvent basicity (Gutmann and Drago criteria) with activation enthalpies for a dissociative mechanism of solvent exchange; and (b) a solventseparated ion pair for the structured solute exchanging a ligand with a dipolar molecule of the bulk solvent. Because of the high degree of uncertainty in the experimental data, the two models for the reaction appear to have equal merit at the present time.
