The reactions in the C{sub 60}-(TiCl{sub 4} + Br{sub 2}) system have been performed in ampoules at elevated temperatures. The molecular structure of the fullerene halides (C{sub 60}Cl{sub 5}){sub 2}, C{sub 60}X{sub 6}, C{sub 60}X{sub 8}, and C{sub 60}X{sub 24} (X = Cl, Br) has been determined and refined using single-crystal X-ray diffraction. It has been established that an increase in the bromine concentration results in an increase in the number of halogen atoms attached to the fullerene cage and in an increase in the relative fraction of bromine atoms in mixed halogen derivatives from almost pure chlorides (C{sub 60}Cl{sub 5}){sub 2} and C{sub 60}Cl{sub 6} to halides C{sub 60}X{sub 8} and C{sub 60}X{sub 24} with a high relative bromine content.
