Abstract: A Series of new substituted ferrocene polyiodides with general formula of [(RC5H4)(R'C5H4)Fe]Ix were synthesized.The elemental analysis showed that substituted ferrocenes with Et, Ac, and ph as Rand R' groups give polyiodides with integer ratios for ferrocene to iodine while ferrocenes with MeCH (OH) substituents give polyiodides with non-integer ratios for ferrocene to iodine. The 57Fe Mossbauer study indicated the oxidation of ferrocenes in these polyiodides to [FcH]+ cations with reduced ISvalues compared to the original-ferrocenes and much reduced (even reached to zero) QSvalues. The IRspectra of these polyiodides also show the presence of [FcH]+ type cations with the characteristic absorptions at 400～500cm-1 (multiplet), the shift of 800-850cm-1 (strong) and characteristic absorptions for substituents to higher wave-numbers.
