| Abstract: | The reaction between Co(en)2(2?pzCO2)2+ (bis-ethylenediamine (2-pyrazinecarboxylato)cobalt(III)) and Fe(CN)5H2O3? (aquopentacyanoferrate(II)) to form the binuclear complex (en)2Co( μ-pzCO2)Fe(CN)5]? has been studied in several isodielectric binary mixtures at 298.2 K (cosolvents: methanol, ethanol, tertbutyl alcohol, ethyleneglycol, and glycerol). Results were rationalized by using a free energy relationship. The importance of correcting the rate constants obtained in the different mixtures from the ionic strength influence has been shown. © 1995 John Wiley & Sons, Inc. |
