Abstract

Rates of electron transfer from a series of one-electron reductants to a nonheme oxoiron(IV) complex, [(N4Py)Fe^IV(O)]²⁺, are enhanced as much as 108-fold by addition of metal ions such as Sc³⁺, Zn²⁺, Mg²⁺, and Ca²⁺; the metal ion effect follows the Lewis acidity of metal ions. The one-electron reduction potential of [(N4Py)Fe^IV(O)]²⁺ is shifted to a positive direction by 0.84 V in the presence of Sc³⁺ ion (0.20 M).
