  • Conformational polymorphism: The missing phase of 1,1,2,2-tetrachloroethane (Cl2HC-CHCl2) 

    Barrio Casado, María del; Tamarit Mur, José Luis; Mondieig, Denise; Zuriaga, Jose Mariano; Perez, Silvina C.; Negrier, Philippe (2013-05)
    Article
    Restricted access - publisher's policy
    Halogenoethane derivatives are known to exhibit different polymorphs involving a different translational, orientational, and conformational order. The 1,1,2,2- tetrachloroethane (Cl2HC−CHCl2) exhibits a normal pressure ...
  • Emergence of glassy-like dynamics in an orientationally ordered phase 

    Romanini, Michela; Negrier, Philippe; Tamarit Mur, José Luis; Capaccioli, Simon; Barrio Casado, María del; Pardo Soto, Luis Carlos; Mondieig, Denise (2012-04-04)
    Article
    Open Access
    The dynamics of a simple rigid pseudoglobular molecule (2-adamantanone) has been studied by means of dielectric spectroscopy and examined under the constraints imposed by the space group of the crystal structure determined ...
  • From figh-temperature orientationally disordered mixed crystals to low-temperature complex formation in the two-component system (CH3)3CBr + Cl3CBr 

    Barrio Casado, María del; Negrier, Philippe; Tamarit Mur, José Luis; Mondieig, Denise (2011-02-02)
    Article
    Restricted access - publisher's policy
    The phase diagram of the two-component systems (CH(3))(3)CBr + Cl(3)CBr has been experimentally determined by means of differential scanning calorimetry and X-ray powder diffraction techniques from the low-temperature ...
  • Polymorphism in 2-X-Adamantane Derivatives (X = Cl, Br) 

    Negrier, Philippe; Barrio Casado, María del; Tamarit Mur, José Luis; Mondieig, Denise (2014-08-14)
    Article
    Restricted access - publisher's policy
    The polymorphism of two 2-X-adamantane derivatives, X = Cl, X = Br, has been studied by X-ray powder diffraction and normal- and high-pressure (up to 300 MPa) differential scanning calorimetry. 2-Br-adamantane displays a ...
  • Polymorphism in halogen-ethane derivatives: CCl3-CCl3 and ClF2C-CF2Cl 

    Negrier, Philippe; Tamarit Mur, José Luis; Barrio Casado, María del; Mondieig, Denise (2013-02-06)
    Article
    Restricted access - publisher's policy
    The polymorphism of hexachloroethane, Cl3C−CCl3, has been reinvestigated by means of X-ray and neutron scattering. The long time unknown structure of the intermediate phase II of Cl3C−CCl3 has been determined as monoclinic ...
  • Polymorphism in halogen-ethane derivatives: CCl3-CF2Cl and CF3-CF2Cl 

    Negrier, Philippe; Barrio Casado, María del; Tamarit Mur, José Luis; Pardo Soto, Luis Carlos; Mondieig, Denise (2012-01-03)
    Article
