| Resumo: | Molecular water oxidation catalysis is a field that has experienced an impressive development over the last decade mainly fueled by the promise of generation of sustainable carbon neutral fuel society, based on water splitting. Most of these advancements have been possible thanks to the detailed understanding of the reactions and intermediates involved in the catalytic cycles. Today’s best molecular water oxidation catalysts reach turnover frequencies that are orders of magnitude higher than that of natural oxygen evolving center in photosystem II. These catalysts are based on Ru complexes where at some stage, the first coordination sphere of the metal center becomes seven coordinated. The key for this achievement is largely based on the use of adaptative ligands that adjust their coordination mode depending on the structural and electronic demands of the metal center at different oxidation states accessed within the catalytic cycle. This Review covers the latest and most significant developments on Ru complexes that behave as powerful water oxidation catalysts and where at some stage the Ru metal attains coordination number 7. Further it provides a comprehensive and rational understanding of the different structural and electronic factors that govern the behavior of these catalysts. |
