The structural properties of solid C84 (mixture of two isomers, D2(IV) and D2d(II) in a 2:1 abundance ratio) were studied by synchrotron X-ray powder diffraction at ambient temperature and elevated pressures. The structure remains strictly cubic to 9.2 GPa with no evidence of a structural phase transition, analogous to those encountered in C60 and C70. The pressure behavior of the intramolecular phonon modes studied by Raman spectroscopy is consistent with the structural results.
