Abstract
Low-chlorinated fullerenes, dimeric (C60Cl5)2 and one-dimensional, polymeric (C60Cl4)∞, were obtained by high-temperature (270 °C) chlorination of C60 with a SbCl5/SbCl3 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.
