Conversion constants for redox potentials measured versus different reference electrodes in acetonitrile solutions at 25°C

Caution should be exercised when one is comparing the redox potentials of complexes measured in CH3CN solutions versus different reference electrodes. A critical review of conversion constants amongst various reference electrodes reported in the literature reveals that in most cases the comparisons of redox potential values are far from accurate. From measurements of relationships amongst various common reference electrodes in CH3CN solutions, conversion constants for redox potentials measured versus different reference electrodes in acetonitrile solutions at 25°C are proposed, along with a convention for reporting redox potential values.
