5,17-Dibromo-26,28-bis[(methoxycarbonyl)methoxy]-25,27-dipropoxy-2,8,14,20-tetrathiacalix[4]arene

Abstract

The title thiacalix[4]arene derivative, C36H34Br2O8S4, adopts an unusual pinched cone conformation with the propoxy-substituted benzene rings inclined inward [forming a dihedral angle of 33.4 (1)°] and with the brominated benzene rings bent outward, making a dihedral angle of 66.1 (1)°. In the crystal, the molecules form chains along [001] via C—H...S hydrogen bonds and S...S contacts [S...S = 3.492 (3) Å]. The chains are associated into bilayers through C—H...O hydrogen bonds, generating an R22(10) motif.
