SYNTHESIS AND CHARACTERIZATION OF THE FULLERENE CO-CRYSTALS C-60-CENTER-DOT-12C(6)H(12), C-70-CENTER-DOT-12C(6)H(12), C-60-CENTER-DOT-12CCL(4), C-60-CENTER-DOT-2CHBR(3), C-60-CENTER-DOT-2CHCL(3), C-60-CENTER-DOT-2H(2)CCL(2)

By crystallization of fullerenes from non-polar solvents (C6H12, CCl4, CHBr3, CHCl3 H2CCl2) compounds of the following compositions were obtained: C-60 (.) 12C(6)H(12), C-70 (.) 12C(6)H(12), C-60 (.) 12CCl(4), C-60 (.) 2CHCl(3), C-60 (.) 2CHBr(3) and C-60 (.) 2H(2)CCl(2). Lattice parameters have been determined by X-ray diffraction of powder samples; according to single-crystal examinations on C-60 (.) 12C(6)H(12), C-60 (.) 12CCl(4) and C-60 (.) 2CHBr(3) the fullerene is orientationally disordered. C-60 (.) 12C(6)H(12), kubisch, a = 28,167(1) Angstrom; C-70 (.) 12C(6)H(12), kubisch, a = 28,608(2) Angstrom; C-60 (.) 12CCl(4), kubisch, a = 27,42(1) Angstrom; C-60 (.) 2CHBr(3), hexagonal, a=10,212(1), c=10,209(1) Angstrom; C-60 (.) 2CHCl(3), hexagonal, a=10,08(1), c=10,11(2) Angstrom;C-60 (.) 2H(2)CCl(2), tetragonal, a=16,400(1) Angstrom, c=11,645(7) Angstrom.
