Abstract

A novel dinuclear iron complex [Fe₂(Pmabt)₂(Pbt)₂][ClO4]₂⋅2CH₃OH(2Fe-4S, Pmbt = 2-(pyridin-2'-yl)benzothiazoline, Pbt = 2-(pyridin2-yl)benzo[d]thiazole) is presented. The electrochemical water oxidation properties manifested that 2Fe-4S exhibits a sevenfold higher TOF value compared to the mononuclear counterpart. Kinetic isotope effects (KIEs) showed the distinct O–O bond formation mechanism of the two complexes, underscoring the significant influence of nuclearity on catalytic behavior in water oxidation processes. © The Royal Society of Chemistry 2025
