Extraction of fullerenes from carbon soot by trichloroethylene has bee
n studied. We have found that C-60 forms a solvate with trichloroethyl
ene (C-60.C2HCl3: a = 31.31(1); b = 10.156(4); c = 10.146(4) Angstrom;
V = 3228.6 Angstrom(3), Z = 4, d(calc), = 1.752 g cm(-3), orthorhombi
c symmetry). Its thermal stability has been studied using TG and DSC.
A phase transition of the first order at 167 K has been detected.
