New Giant Fullerenes Identified as Chloro Derivatives: Isolated-Pentagon-Rule C-108(1771)Cl-12 and C-106(1155)Cl-24 as well as Nonclassical C104Cl24
High temperature chlorination of HPLC fractions of higher fullerenes followed by single crystal X-ray diffraction with the use of synchrotron radiation resulted in the structure determination of IPR C-106(1155)Cl-24 and IPR C-108(1771)Cl-12. C-106(1155)Cl-24 is cocrystallized with C104Cl24, a chloride of the non-classical isomer of C-104. The moderately stable isomer C-106(1155) and the most stable C-108(1771) represent so far the largest pristine fullerenes with known cages.
