1,3-Alternate conformer 5,11,17,23-tetra-tert-butyl-25,26,27,28-tetra­kis­(4-methyl­sulfanylbenz­yloxy)-2,8,14,20-tetra­thia­calix[4]arene

Abstract: The title thia­calix[4]arene derivative, C72H80O4S8, adopts a 1,3-alternate conformation, where the four 4-methyl­sul­fan­yl­benzyl groups are located alternately at the two sides of a virtual plane defined by the four bridging S atoms. In the crystal, there are no significant inter­molecular inter­actions present. Some of the peripheral tert-butyl and methyl­sulfanyl groups are disordered over two positions. A region of disordered electron density, occupying voids of ca 700 Å3 for an electron count of 124, was treated using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155].
