Stepwise 6H⁺/6e^- Electron-Coupled Proton Buffers Based on Fe and Redox-Active Ligands.

ABSTRACT: Herein, we report electron-coupled-proton buffers (ECPBs) based on Fe and redox-active ortho-phenylenediamine (opda) ligands that perform stepwise and reversible 6H⁺/6e^- transformations. Four of the Fe complexes involved in the PCET transformation (namely ^X6²⁺, ^X8H₂²⁺, ^X10H₄²⁺ and ^X12H₆²⁺) were structurally and/or spectroscopically characterized. The reductive protonation of ^X6²⁺ to ^X12H₆²⁺ and the oxidative deprotonation of ^X
