      The co-crystal of C60·2CBrClH2 possesses a monoclinic (C2/m) structure at room temperature with both molecular entities, C60 and CBrClH2, orientationally ordered. At 322 K, it transforms reversibly into a hexagonal (P6/mmm) ...
    • C60 solvate with (1,1,2)-trichloroethane: dynamic statistical disorder and mixed conformation 

      Mitsari, Efstratia; Romanini, Michela; Qureshi, Navid; Tamarit Mur, José Luis; Barrio Casado, María del; Macovez, Roberto (2016-05-27)

      We present a full characterization of the orientationally disordered cocrystal of C-60 with (1,1,2)-triChloroethane (C2H3Cl3), by means of X-ray diffraction, Raman spectroscopy, and broadband dielectric spectroscopy. Our ...

    • Ordered and disordered solvates of C 60 and CBrCl 2 H 

      Ye, Jin; Barrio Casado, María del; Céolin, René; Qureshi, Navid; Negrier, Philippe; Rietveld, Ivo B.; Tamarit Mur, José Luis (2019-01-01)

      The formation of co-crystals is often unexpected; however, the Buckminster fullerene, for which many solvates are known,is an excellent system to study this tendency. In the present paper, C60 and CBrCl2H co-crystals have ...
    • Orientational order in the stable buckminster fullerene solvate C60·2CBr2H2 

      Ye, Jin; Barrio Casado, María del; Negrier, Philippe; Qureshi, Navid; Rietveld, Ivo B.; Céolin, René; Tamarit Mur, José Luis (2017-04-01)

      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, ...
    • Van-der-Waals based solvates of C-60 with CBr2Cl2 and CBr2(CH3)(2)

      We demonstrate that solvates of fullerene C60 form very predictable structures with finely tunable properties through the choice of the second component or solvent. Cubic co-crystals of C60·12CCl2Br2 and C60·12CBr2(CH3)2 ...
