Popis: The title compound, C(47)H(60)O(6).3CHCl(3), is the first example of a lower-rim mono-ester calixarene derivative to be crystallographically characterized. The cone conformation adopted by the macrocycle is stabilized by three intramolecular hydrogen bonds. Self-inclusion of the methyl ester chain in the cavity of an adjacent molecule gives rise to infinite chains parallel to the c axis. C-H...pi interactions involving the methyl group most imbedded in the cavity contribute to the stabilization of the system.
