✦ Synopsis

This report reccmmends that the redox couples ferrocene/ ferricenium ion Lferrocene: bis(?-cyclopentadienyl)iran(II)1 and bis(biphenyl)chrcrrium(I)/bis~biphenyl)chromium(O) be employed as reference redox systems. Procedures for measuring and reporting electrode potentials in nonaqueous solvents versus these reference redox systems are presented. The difference in electrode potentials for ferrocene/ ferriceniun; ion and bis(biphenyl)chrcmium(0)/bis(biphenyl)chrcmium('i) ion for 22 solvents obtained by polarography and cyclic voltammetry are listed. Both of the reccmnended redox systems approach a solvent independent redox system as closely as presently known. Electrode potential data reported versus these systems permit the comparison of electrode potentials for a given system in different nonaqueous solvents and thus allow studies of solvent effects on electrode potentials in nonaqueous systems by compiling and comparing data obtained in different solvents.
