A reversible proton relay process is demonstrated for a Fe 2 complex possessing a terminal thiolate in the presence of nitrogen‐based acids. The process is temperature dependent as the hydrogen‐bonding pair between the thiolate and the acidic proton is converted to the Fe–hydride species upon temperature increase. The alternating proton‐donating/‐accepting ability for the corresponding trio of sites—the Fe 2 core, the terminal S, and the N(amine)—is highly dependent on the well‐tuned p K a value of every site.
