Iron chalcogenide clusters are essential for numerous metalloproteins such as the Rieske-protein and bacterial nitrogenases. The latter are enzymes which catalyze the reduction of N2 to NH3, whereas an iron sulfur cofactor constitutes the active site for substrate binding and conversion. The cleavage of the central Fe−S−Fe unit is proposed to be a key step for substrate activation. Molecular models of this subunit that might give valuable insights into its properties are rare. Herein, we report the synthesis of novel low coordinate iron chalocogenido complexes from the reaction of an iron(I) precursor and elemental chalcogen. The complexes were characterized concerning their electronic structure and first reactivity studies towards nitrogenasis relevant substrates are presented.
