Under mild conditions , a linear polymeric (C 70 2− ) n fulleride was synthesized as single crystals which allow, for the first time, a complete structural analysis of a polymeric fulleride. Starting from the strongest “disturbance” of the cage geometry at the linkage sites, the pronounced alternation of the bond lengths decreases towards the middle of the C 70 units (see Schlegel diagram of the C 70 2− building block; color coding of the bond lengths [Å]: blue <1.39, black 1.39–1.47, red 1.47–1.52 Å, green >1.52).
