Abstract

Abstract : The synthesis of a very low-coordinate diferrous [2Fe–2S] 0 unit is presented which shows exceptionally strong antiferromagnetic coupling between the iron ions. Abstract : 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 CS2 is also shown.
