An impurity aids in the purification of C60. A 1:1 complex of C60 and calixarene crystallizes from toluene (see picture) with the fullerenes organized in a one-dimensional zigzag array shrouded by a sheath of calixarenes. The complex forms in the presence of other globular molecules including C70, the major impurity in fullerite.
