| Outline of Final Research Achievements |
Multi-redox reactions such as nitrogen fixation (N2 + 6H+ + 6e- → 2NH3) and oxygen evolving reaction (2H2O → O2 + 4H+ + 4e-) can be effectively catalyzed by multinuclear metal complexes embedded in proteins (nitrogen fixation: Fe7Mo octanuclear complex; oxygen evolving reaction: Mn4Ca pentanuclear complex). In this research, we have synthesized a series of novel multinuclear metal complexes and investigated their electrochemical properties and catalytic activity for multi-redox reactions. As a result, we have succeeded in (1) elucidation of crystal structures and electronic properties of three distinct redox states of an oxo-bridged dinuclear ruthenium complex and (2) development of a pentanuclear iron catalyst for water oxidation.
