摘要：
Two solvated crystals of C-60 were formed from CCl4 solutions. It was found that the cubic solvated crystal is composed of a C-60(CCl4)(13) formula unit while the hexagonal crystal has a C-60(CCl4)(2) unit. These solvates have phase behavior comparable with that of cyclohexane solvates of C-60, being closely related to binary sphere mixtures with a characteristic diameter ratio of 0.58. The present calorimetric study strongly suggests that the C-60(CCl4)(13) crystal has an AB(13)-type structure, in which icosahedron clusters of CCl4 like those in the cyclohexane analogue are formed.
