Abstract

We have synthesized and structurally characterized a series of organoboron-modified cyanometalates. The redn. potentials of these modified metal complexes can be tuned over a wide range by variations in the Lewis acidities of the appended organoboron derivs. We have found half-wave potential shifts of +250 mV/BPh_3 and +380 mV/B(C_6F_5)_3, with total shifts of +1.5 and +2.1 V, resp., relative to the parent M^(III/II) (M = Mn, Fe) redox couples. Selected highly sol. complexes are attractive candidates for use in flow batteries, as their redox pairs exhibit electrochem. reversibility over a wide potential range in nonaq. solvents.
