The synthesis of bis[(3a,4,5,6,6a-η)-1,3,4,5,6-pentamethylcyclopenta[d]imidazo-2-thionoyl]iron(II) is reported. Structural determination of the unusual hetero-substituted metallocene by X-ray crystallographic analysis is described. Preliminary electrochemical studies reveal that oxidation and reduction potentials for the subject ferrocene lie midway between those of ferrocene and decamethylferrocene.

A sterically protected biradical species, 1-tert-butyl-3-methyl-2,4-bis(2,4,6-tri-tert-butylphenyl)-1,3-diphosphacyclobutane-2,4-diyl was allowed to react with tris(4-bromophenyl)ammoniumyl hexachloroantimonate as an oxidant and the product was analyzed by EPR to show that the biradical was oxidized to give the corresponding radical cation species. The structure of the cation radical was also supported by ab initio calculations on a model compound.
