✦ Synopsis

The reaction between Co(en)2(2-pzCO~)~' (bis-ethylenediamine (2-pyrazinecarboxylato)cobalt(III)) and Fe(CN)5H203-(aquopentacyanoferrate(I1)) to form the binuclear complex [(en)aCo( pL-pzC02)Fe(CN51-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.
