A water-soluble copper(II) complex of the dianionic tridentate pincer ligand bearing a Cu-bound carbonate group is examined as a water oxidation catalyst. With computational evidence, this Cu-bound carbonate may act as a proton shuttle to remove protons for water activation, including steps toward catalytically active species and its subsequent O−O bond formation. This carbonate group is likely to resemble the key role of an intramolecular base to improve catalytic water oxidation performance.
