Abstract/OtherAbstract:
A biomimetic [2Fe-2S] cluster has been isolated in the fully reduced diferrous form and characterized by X-ray diffraction. This completes a consistent series of synthetic analogues of protein-bound [2Fe-2S]z redox centers (z = 2+, 1+, 0) with identical capping ligands. 57Fe Mössbauer data of the extremely oxidation-sensitive complex compare well with those of the very few reports of all-ferrous ferredoxins and Rieske centers; they confirm the S = 0 ground state and establish an upper limit for the exchange coupling, J ≤ -90 cm-1.
