In the title solvated calixarene, C47H60O4 center dot 2CHCl(3), the host chalice displays an almost undistorted cone conformation, stabilized by three strong O-H center dot center dot center dot O hydrogen bonds at the calixarene's lower rim. One chloroform solvent molecule is fixed in the calixarene cavity by C-H center dot center dot center dot pi interactions, while the second is accommodated in a clathrate-like mode in elliptical packing voids. These voids are spanned by six host molecules connected via C-H center dot center dot center dot pi contacts and van der Waals interactions. Within the crystal structure, one tert-butyl group of the calixarene host is disordered over two orientations, with occupancies of 0.884 (4) and 0.116 (4). Furthermore, both solvent molecules show disorder, with occupancies of 0.857 (2) and 0.143 (2) for the cavitate-type, and 0.9359 (17) and 0.0641 (17) for the clathrate-type chloroform solvent molecules.
