Dimeric and 1D polymeric low-chlorinated C 60 fullerenes, (C 60 Cl 5 ) 2 and (C 60 Cl 4 ) ∞ .

Low-chlorinated fullerenes, dimeric (CCl) and one-dimensional, polymeric (CCl), were obtained by high-temperature (270 °C) chlorination of C with a SbCl/SbCl mixture, as revealed by X-ray crystallography. The compounds were characterized by IR and Raman spectroscopy and theoretical calculations. This is the first observation of a fullerene polymer with single C-C bonding and neutral building blocks.
