C60F20: “Saturnene”, an Extraordinary Squashed Fullerene

Abstract: In our program of fluorinating fullerenes by metal fluorides under vacuum followed by HPLC separation of the products, we have isolated and in many cases fully characterized the following: C

“…Distortions of the cage in such areas are so significant that prominent concavities are formed (Figure 3). This allows us to add an “indented” fullerene molecule C 60 F 48 to the previously reported series of distorted cages of fluorofullerenes: C 60 F 18 —a flattened cage7 and C 60 F 20 —a squashed fullerene 10…”

“…Among the reactions reported is a selective synthesis of the composition C 60 F 44 . We also report a nonchromatographic purification of the previously reported FF C 60 F 20 14. This alternative technique enabled us to verify the proposed Saturn‐like structure of this compound by X‐ray crystallography.…”

“…However, C 60 also sublimes out of the hot zone at these temperatures, which significantly lowers the conversion of C 60 into FFs. Furthermore, although C 60 F 18 can be prepared selectively in high yield as a single isomer,11 the homologous composition C 60 F 20 , which is only known as a single isomer that cannot be formed by the addition of two F atoms to C 3 v ‐C 60 F 18 , cannot: it has only been prepared as a minor impurity in FF syntheses 14. Therefore, we were pleased to discover that LiMnF 4 is a more effective FA for the production of FFs with n =2, 4, 6, 8, and 20 than most other FAs we have examined to date, although even with LiMnF 4 these compounds are only formed in minor amounts relative to C 60 F 18 .…”
