title: 5,17-Dibromo-26,28-bis-[(meth-oxy-carbon-yl)meth-oxy]-25,27-diprop-oxy-2,8,14,20-tetra-thia-calix[4]arene.
abstract: The title thia-calix[4]arene derivative, C(36)H(34)Br(2)O(8)S(4), adopts an unusual pinched cone conformation with the prop-oxy-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 mol-ecules 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 R(2) (2)(10) motif.
