Syntheses of the following disulfide-containing dinuclear and tetranuclear organoiron compounds are described: [Cp2Fe2(S2)(SR)2]0,1+, [Cp4Fe4S5]0,1+,2+, and [Cp4Fe4S6] (Cp = η5-C5H5). The compounds have been characterized by spectroscopic, electrochemical, and chemical properties. Temperature-dependent 1H NMR spectroscopy indicates fluxionality of the triply bridging disulfide ligand in Cp4Fe4S5n (n = 0 and 2+). The cluster products resulting when these disulfide-containing complexes are chemically or electrochemically oxidized, including [CpFe(SR)(NCMe)]22+, and adducts formed with other metals via the electron-rich disulfide ligands are discussed.
