Nuclearity effect on water oxidation: a comparative study of dinuclear and mononuclear iron complexes
A novel dinuclear iron complex [Fe<sub>2</sub>(Pmabt)<sub>2</sub>(Pbt)<sub>2</sub>][ClO<sub>4</sub>]<sub>2</sub>·2CH<sub>3</sub>OH (2Fe-4S, Pmbt = 2-(pyridin-2'-yl)benzothiazoline, Pbt = 2-(pyridin-2-yl)benzo[<i>d</i>]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.
