None:
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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
