Abstract
The title compound, 7,13,21,27-tetra-tert-butyl-3,17-dioxa-pentacyclo[23.3. 1.1(5,9).1(11,15).1(9,23)]ditriaconta-1(29),5,7,9(30),-11(31),12,14,19(32), 20,22,25,27-dodecaene-29,30,31,32-tetraol, crystallizes as a solvate with o ne molecule of chloroform and one molecule of tetrahydrofuran, C46H60O6. CH Cl3.C4H8O. The calixarene assumes a cone-like conformation stabilized by in tramolecular hydrogen bonds involving both phenolic and ether O atoms. The two solvent molecules are located in each of the two half-cone cavities of the calixarene.
