High-temperature (360 °C) chlorination of C70 with VCl4 or SbCl5 yields only IPR C70Cl26/28. Chlorination with SbCl5 at 440 °C resulted in a skeletal transformation via a two-step Stone-Wales rearrangement and the formation of non-IPR 8005C70Cl26 with two fused pentagon pairs in the carbon cage which was established by single crystal X-ray diffraction.
