1,4,7,10-Tetraoxacyclododecane-triphenylmethanethiol (1/2)

Abstract: In the centrosymmetric formula unit of the title complex, C₈H₁₆O₄·2C₁₈H₁₆S, the 1,4,7,10-tetraoxacyclododecane molecule adopts the biangular [66] conformation, and the triphenylmethanethiol molecules are linked to the macrocycle via a long S-HO hydrogen bond [SO = 3.460 (2) Å and S-HO = 161 (2)°]. Attractive interactions of phenyl groups in edge-to-face conformations combine inversion-related formula units into chains running along the [111] direction in the crystal structure. Association of the chains into sheets is achieved via C-H [bold pi] interactions.

Formula: C₈H₁₆O₄·2C₁₉H₁₆S
