Here we present the synthesis of a unique diferrous [2Fe-2S] 0 complex with only three-coordinate iron ions via reduction of a four-coordinate diferric [2Fe-2S] 2+ complex with concomitant ligand loss. The obtained compounds were thoroughly examined for their properties ( e.g. by 57 Fe Mössbauer spectroscopy and magnetic susceptibility measurements). Facile cleavage of the [2Fe-2S] rhombus, commonly seen as rather stable, by CS 2 is also shown.
