1-Ferrocenly　methyl-2-ferrocenly　benzimidazole　was　sythesized　by　the　reaction　of　o-phenylenediamine　with　ferrocenecarboxaldehyde　in　the　condition　of　toluenesulfonic　acid　as　catalyst.　Iodized　salts　(3,　4)　of　1-ferrocenyl　methyl-2-ferrocenyl-3-alkylbenzimidazolium　were　formed　by　the　reaction　of　compound　2　with　alkyl　iodide.　Hexafluorophosphate　salts　(5,　6)　and　bis(trifluoromethane　sulfonimide)　salts　(7,　8)　of　1-ferrocenyl　methyl-2-ferrocenyl-3-alkylbenzimidazolium　were　obtained　by　the　anion　exchange　reaction　of　compounds　3　and　4.　All　of　these　salts　were　characterized　by　H-1　NMR,　C-13　NMR,　IR,　MS,　HRMS　and　elemental　analysis.　In　the　crystal　of　compound　5,　the　compound　was　assembled　to　a　chain　supramolecular　structure　along　axis　c　by　the　intermolecular　hydrogen　bonds.　Electrochemical　analysis　demonstrated　that　the　quasi-reversible　oxidation　waves　split　double　of　Fe　in　ferrocene　fragment　of　compounds　3　similar　to　8;　UV-Vis　absorption　spectra　show　that　these　salts　possess　photoinduced　charge　migration　phenomenon.　And　the　iodized　salts　presented　good　catalytic　effect　on　decomposition　of　ammonium　perchlorate　(AP)　in　DSC-TG　test.
