Fullerene C60, 2CCl4 solvate. A solid-state study

By slowly evaporating solutions of fullerene C60 in CCl4 at room temperature, a stable solvate (C60, 2CCl4) crystallizes in a simple hexagonal system (Laue class 6/mmm) with a = 10. 10(5) angstrom and c = 10.75(5) angstrom. This solvate undergoes a phase transition at 210-220 K and decomposes at 397 K. Atomic force microscopy of the (001 ) face shows a C60 molecular packing analogous to that which exists in the {111} planes of face-centered cubic C60. It seems likely that C60 and CCl4 molecules are orientationally disordered at room temperature.
