N2 - The low temperature orientationally ordered structure of C60 consists of rapid reorientation between two structurally distinct configurations. At ambient pressure, the lower-energy orientation, described by pentagons facing (110) bonding directions. has a larger volume than the second orientation, described by hexagons facing (110). In this paper, it is shown that application of a modest pressure of around 2 kbar is sufficient to make the 'hexagon orientation' the more energetically favourable. indicating that the structural ground state of C60 is highly pressure dependent.
