Pressure dependence of the structural phase transition in C60
G. Kriza,J.-C. Ameline,Denis Jérome,A. Dworkin,Henri Szwarc,Claude Fabre,D. Schütz,André Rassat,Patrick Bernier,Ahmed Zahab +9 more
TL;DR: In this article, the effect of hydrostatic pressure on the temperature of the structural phase transition in crystalline C6o is investigated by differential thermal analysis in the pressure range of I bar to 5 kbar.
Fullerene C60, 2CCl4 solvate. A solid-state study
René Céolin,Viatcheslav N. Agafonov,Daniel André,A. Dworkin,Henri Szwarc,Jerôme Dugué,Bieneta Keita,Louis Nadjo,Claude Fabre,André Rassat +9 more
TL;DR: By slowly evaporating solutions of fullerene C60 in CCl4 at room temperature, a stable solvate (C60, 2CCl4) crystallizes in a simple hexagonal system as discussed by the authors.

Molecular packing of fullerene C60 at room temperature
Daniel André,A. Dworkin,Henri Szwarc,René Céolin,Viatcheslav N. Agafonov,Claude Fabre,André Rassat,Leo Straver,Patrick Bernier,Ahmed Zahab +9 more
TL;DR: In this article, a single crystal of C60 grown from a toluene solution has been studied by X-ray diffraction at room temperature, and the lattice is face-centered cubic, with space group Fm3m and Z = 4.

Dilution Effects in a Spin Crossover System, Modelled in Terms of Direct and Indirect Intermolecular Interactions
H. Constant-Machado,Jorge Linares,François Varret,Jaap G. Haasnoot,J.P. Martin,Jacqueline Zarembowitch,A. Dworkin,Azzedine Bousseksou +7 more
TL;DR: In this paper, Monte Carlo simulations of the thermal variation of the high-spin fraction, using a two-level Ising-type Hamiltonian, have been performed by introducing an indirect interaction of the spin-crossover units via the non-spin crossover unit, the origin of which is discussed in steric terms.
Thermal studies of C60 transformed by temperature and pressure treatments
A. Dworkin,Henri Szwarc,V. A. Davydov,L. S. Kashevarova,A.V. Rakhmanina,V. N. Agafonov,René Céolin +6 more
TL;DR: In this paper, it is confirmed that mixtures of rhombohedral and tetragonal structures are formed in the 2-4 GPa and 673-1073 K pressure-temperature domain.
