Initial electrochemical studies of C[sub 84] in benzonitrile (PhCN) and o-dichlorobenzene (ODCB) have been reported but did not clearly distinguish between these two isomers. We have reproduced these electrochemical results in benzonitrile (PhCN) as well as carried out new experiments in pyridine and a 15/85 dimethylformamide (DMF)/toluene mixture and have observed that two distinct sets of multiple redox processes can be resolved in the latter solvents, each of which can be associated with reduction of a different isomer. Combined electrochemical and electron spin resonance (ESR) measurements are now reported in these two new solvents which allow us to assign, for the first time, both half-wave potentials and ESR parameters to a given D[sub 2] or D[sub 2d] C[sub 84][sup n[minus]] isomer, where n = 1, 2, or 3. 21 refs., 2 figs., 1 tab.
