^aThe g_eff value of the most intense, positive signal at low field (see Figure S6).

^bHyperfine splitting of six-line signals observed near g = 5.7 – 5.8 (see Figure S6).

^cCathodic peak potential versus SCE. Data for [Mn^IV(O)(N4py)]²⁺ comes from reference ²⁶ and data for [Mn^IV(O)(^DMMN4py)]²⁺and [Mn^IV(O)(2pyN2Q)]²⁺ comes from reference ⁶.
