E. Abdelhak, D. Merle, M. Perrin and A. Thozet

Abstract: In the complex between p-cumylcalix[4]arene and para-xylene [systematic name: 4-(2-phenylisopropyl)calix[4]arene-1,4-dimethylbenzene (1/1)], C₆₄H₆₄O₄·C₈H₁₀, the macrocycle has a cone conformation, which is stabilized by intramolecular hydrogen bonds. The guest para-xylene molecule is situated inside the cavity, giving an endo-calix complex. The host and guest molecules both have twofold rotation symmetry.
