Medium imparts changes in redox reactions of metal complexes. That is, solvent plays an important role in trapping the exchanging electron on one site similar to that of intramolecular structural changes. Especially in ionic reactions, ion can be thought of creating a polarization field in the surrounding solvent. The rationality behind the proposal of the kinetics was detailed by fit the data in correlation equation involving linear and multiple Grunwald-Winstein plot, Swain's dual linear relationship and Kamlet-Taft's equations. The kinetic inferences of outer-sphere electron transfer reactions of cobalt(III) aryl amine complexes (Co III (pn)2Cl(L) 2+ where L = RC6H5NH2, R = m-OCH3, p-F and H) with MeOH/dioxane solvent content were explored at different temperatures.
