Truly cationic metallocenes with the parent cyclopentadienyl ligand are so far unknown for the Group 14 elements. Herein we report on an almost "naked" [SnCp] cation with the weakly coordinating [Al{OC(CF ) } ] and [{(F C) CO} Al-F-Al{OC(CF ) } ] anions. [SnCp][Al{OC(CF ) } ] was used to prepare the first main-group quadruple-decker cation [Sn Cp ] again as the [Al{OC(CF ) } ] salt. Additionally, the toluene adduct [CpSn(C H )][Al{OC(CF ) } ] was obtained.
