Association and orientation of C70 on complexation with calix[5]arene.
Calix[5]arene and C70 in p-xylene form a ball-and-socket supramolecular complex with the C5 axis of the fullerene tilted 40 degrees relative to the symmetry axis of the calixarene, the extended structure is comprised of well-separated zigzag sheets of C70 molecules.
