Abstract

A novel dinuclear iron complex [Fe₂(Pmabt)₂(Pbt)₂][ClO₄]₂·2CH₃OH (2Fe-4S, Pmbt = 2-(pyridin-2′-yl)benzothiazoline, Pbt = 2-(pyridin-2-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.
