The existence of the fully fluorinated fullerene, C60F60, is still subject to controversy. Mass spectrometric evidence shows that it exists, albeit in trace amounts five orders of magnitude in concentration below the most abundant C60F40-42. Generall

In order to better understand the properties and composition of solids of polyfluorinated C[sub 60], X-ray photoelectron spectroscopy (XPS) was used to characterize several different C[sub 60]F[sub x] samples synthesized in two different laboratories

AC impedance and x-ray diffraction measurements versus temperature and pressure on several ternary fullerene intercalation compounds are reported. The results support our previously established empirical correlation between superconducting onset temp

Electron-capture negative ion chemical ionization (EC-NICI) and field desorption (FD) mass spectrometric techniques were utilized to examine polyfluorinated C60. Two different samples from the same preparation, one prior to sublimation and the other

Solid C[sub 60] reacts with low-pressure fluorine at 300 K, yielding yellow-to-white solids which are air-stable for long periods, with average compositions in the range C[sub 60]F[sub 35-44]. Mass spectrometry reveals broad distributions of F/C rati

A theoretical computation of vibrational anharmonicity is presented which is a generalization of the simple Gruneisen approach. The calculation was based on a model that defines a simple relationship between the binding energy of a solid and the vari

A spherically averaged potential was used to calculate solid state properties for C{sub 70} in the disordered fcc phase. Each molecule was treated as a spherical shell of 70 carbons with radius of 3.8 A, determined by fitting the equation of state to

METALLIC and superconducting donor-type intercalation compounds of C60 are now well established. These involve electron transfer from a sublattice of alkali-metal dopants to a sublattice of fullerene molecules. Three stoichiometric phases have been i

Although fullerenes and their compounds are very new and exhibit new phenomena, pressure has already been an important factor in the characterization and study of these materials. In order to illustrate this, we will review collaborative studies on:
