摘要：

Clathrate type single crystals with the composition of C60(n-C5H12)0.88(C7H8)0.05 were grown from C60- toluene- petroleum ether solution. The structure of the crystals, determined by X-ray diffraction is b-face centered orthorhombic. No phase transition, corresponding to the orientational ordering is observed at 250 K by differential scanning calorimetry. Around 420 K the solvent molecules are released from the clathrate as determined by thermogravimetry-mass spectrometry. An irreversible phase transition is observed simultaneously with the evolution of solvents, resulting in the face centered cubic structure of pure C60.
