Redox Isomerism in the S3 State of the Oxygen-Evolving Complex Resolved by Coupled Cluster Theory.

Chemistry 2021 Jul 19. Epub 2021 Jul 19.

Max-Planck-Institut für Kohlenforschung, Molecular Theory and Spectroscopy, Kaiser-Wilhelm-Platz 1, 45470, Muelheim an der Ruhr, GERMANY.

The electronic and geometric structures of the water oxidizing complex of Photosystem II in the steps of the catalytic cycle that precede dioxygen evolution remain hotly debated. Recent structural and spectroscopic investigations support contradictory redox formulations for the active-site Mn4CaO x cofactor in the final metastable S3 state. These range from the widely accepted Mn(IV)4 oxo-hydroxo model, which presumes O-O bond formation to occur in the ultimate transient intermediate (S4) of the catalytic cycle, to a Mn(III)2Mn(IV)2 peroxo model representative of the contrasting "early-onset" O-O bond formation hypothesis.
