Further insights into the function of chloride in the water‐oxidizing enzyme system of photosynthesis are provided by the title reaction, in which an Mn 4 III ‐complex is converted into an Mn 4 III Mn IV complex, as given formally in Equation (a). Thus, the redox process S 1 → S 2 taking place in the active state in nature is copied, and suggests that also the biological relevance of Cl ⊖ could lie in the stabilization of a higher oxidized Mn aggregates.
