Dimer C-60 solids are monoclinic crystals with molecular longer axis aligne
d along the c-axis. A simple model based on atom-atom potential used to cal
culate various bulk, structural and thermodynamic properties of this fuller
ite, has also been used to investigate the pressure and temperature depende
nt properties such as bulk modulus, lattice and orientational structure, ph
onon dispersion relations, Gruneisen parameters, heat capacity and entropy.
An important feature of this solid evidently concerns its anisotropic pres
sure compression. We calculate these directional compressibilities and find
the anisotropy for pressure compression very significant. It is expected t
hat the properties of dimer solid C-60 calculated here will motivate furthe
r experimentation on this solid.
