Great sharing: The facile formation of the complete redox series of biomimetic [2Fe-2S] clusters 1 to 3 supported by β-diketiminato ligands is reported. The reduced mixed-valence [2Fe-2S] cluster 2 represents a unique biomimetic [2Fe-2S] cluster anion with an extensively delocalized Fe2+Fe3+ pair as evidenced by 57Fe Mössbauer and XAS/XES spectroscopy and supported by DFT calculations.
