N,N,N-Triethylethanaminium 5,11,17,23-tetra-tert-butyl-25-cyanomethoxy-26,28-dihydroxy-27-oxido-2,8,14,20-tetrathiacalix[4]arene: a molecular salt
In the title molecular salt, C8H20N+C42H48NO4S4, the conformation of the anionic tetrathiacalix[4]arene, which is cone-shaped, is primarily determined by intramolecular O—HO hydrogen bonds. There are also intramolecular C— HO short contacts present. In the crystal, the anions (A) and cations (C) are linked by C—HO and C—HS hydrogen bonds, forming –A–C–A–C– chains along [001]. The chains are linked via C—HNcyano ... إقراء المزيد
