摘要：

A series of novel single crystalline C60Xy clathrates were prepared with various guest materials by crystallization from organic solvent-precipitant systems. Four different stoichiometric compositions (y=1, 3/4, 2/3 and 1/2) were found. The stability of the clathrates was studied by thermoanalytical methods. The crystal structures were determined by X-ray diffraction. Based on the stoichiometry and structure, the clathrates are classified as members of two related homologous series with compositions of (C60)m+2X3 and (C60)n+1X2. The first observations of birefringence and phase transitions corresponding to orientational ordering are demonstrated.
