Compressibility of C60 between 150 and 335 K and up to 1 GPa

• The bulk modulus B of C60 has been measured in the range 150-335 K and up to 1 GPa, for the first time in the f.c.c. rotationally disordered phase, through the f.c.c. → s.c. transition, and in the s.c. phase. At 298 K we find B values of 8.8 (s.c.) and 6.8 GPa (f.c.c.), significantly lower than those found in previous studies. At the transition B decreases with decreasing V, which is probably an effect of orientational ordering on intermolecular interactions.
