Abstract:
[2Fe2S] synthetic model complexes serve as benchmarks for intermediates proposed in enzyme catalysis, and elucidate how structural effects influence the electronic structure of the cluster. Access to [2Fe2S]1+ complexes has been synthetically challenging, with most clusters degrading or aggregating upon reduction. Here, we report an 2Fe2S cluster ligated by a dinucleating bis(β-diketiminate) cyclophane in two oxidation states, with the reduced congener being valence localized based on X-ray diffraction and Mössbauer data.
