Résumé en anglais

Crystals of the solvate C 60 ·2CBr 2 H 2 (monoclinic C2/m), which is stable in air, were grown by slow evaporation of solutions of C 60 in CBr 2 H 2 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 Å 3 indicate the presence of strong intermolecular interactions between C 60 and CBr 2 H 2. The strong intermolecular interactions are consistent with an overall orientational order for the C 60 and the CBr 2 H 2 molecules in the solvate as found by the Rietveld refinement of its crystal structure.< Réduire
