| Abstract: | Ampoule reactions of C70 with n- and i-C3F7I were carried out at 250-310 °C. Two step HPLC separations allowed the isolation of several C70(n-C3F7)4-8 and C70(i-C3F7)4 compounds. Crystal and molecular structures of C70(n-C3F7)8-V, C70(n-C3F7)6O, C70(n-C3F7)4, and three isomers of C70(i-C3F7)4 have been determined by X-ray crystallography using synchrotron radiation. Molecular structures of the new compounds were compared with the known examples and discussed in terms of addition patterns and relative energies of their formation. |
