摘要：

Crystals of the solvate C60·2CBr2H2 (monoclinic C2/m), which is stable in air, were grown by slow evaporation of solutions of C60 in CBr2H2 at room temperature. The high enthalpy change for the complete desolvation process, 54.9 kJ mol−1 of solvent, as well as the relatively large negative excess volume of −49.6 Å3 indicate the presence of strong intermolecular interactions between C60 and CBr2H2. The strong intermolecular interactions are consistent with an overall orientational order for the C60 and the CBr2H2 molecules in the solvate as found by the Rietveld refinement of its crystal structure.
