摘要：

The crystal structure of buckminsterfullerene C60 (depicted on the right) determined below 249 K shows a temperature-dependent two-fold orientational disorder of the molecules with DELTA-H = 1.06(5) kJ mol-1 and DELTA-S = 0.0(4) JK-1mol-1. In agreement with the small energy difference, the intermolecular contacts are found to be very similar for both molecular orientations. The C-C bond lengths are 1.450(3) and 1.387(3) angstrom.
