The redox reaction of tris(acetylacetonato)iron(III) (Fe(acac)3) on a glassy carbon electrode was investigated in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA). A one-electron transfer redox reaction of [Fe(acac)3]0/− showed the relatively negative potential of −1.4 V vs. Ag|Ag(I). The diffusion coefficient of Fe(acac)3 estimated by chronoamperometry was (1.4 ± 0.1) × 10−7 cm2 s−1. The redox properties examined in this study suggested that the redox reaction of [Fe(acac)3]0/− can be utilized in the negative half-cell reaction of redox flow batteries.
