The present invention relates to a process for the preparation of linear, cyclic and/or cage-type perhalogenated oligosilyl and polysilyl anions by reacting perhalogenated monosilanes, oligosilanes or polysilanes with organosubstituted ammonium and/or phosphonium halides at temperatures ranging from −80° C. to 85° C., preferably −80° C. to 60° C., and to oligosilyl and polysilyl anions prepared according to that process.
