title: An order-disorder phase transition in the structure of C60·4benzene.
abstract: A reversible, broad, order-disorder phase transition in the structure of C(60)·4benzene has been observed to take place with an inflection point at 134 K. In the low-temperature structure fullerene disorder is removed, although the average atomic displacement parameters differ for the two C(60) molecules in the asymmetric unit. Some benzene disorder persists, even at 13 K.
