Abstract: The title calixarene compound [systematic name: 3,9,15,34-tetra-tert-butyl-19,29-dioxa-24-thiahexacyclo[220.127.116.11,11.132,36.05,30.013,18]nonatriaconta-1(30),2,4,7,9,11(39),13,15,17,32,34,36(38)-dodecaene-38,39-diol], C52H70O4S, displays a cone-like conformation, the opposite arene rings bridged by the monothiacrown-3 unit are nearly parallel [dihedral angle = 16.01 (18)°], whereas the other opposite arene rings are twisted to each other at an angle of 74.41 (17)°. Intramolecular O-HO hydrogen bonds help to stabilize the molecular structure. In the crystal, a C-H interaction occurs. One of the tert-butyl groups is disordered over two sets of sites with a site-occupancy ratio of 0.70:0.30.
