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].
