N,N,N-Tri-ethyl-ethanaminium 5,11,17,23-tetra-tert-butyl-25-[(eth--oxy-carbon-yl)-meth-oxy]-26,28-dihy-dr-oxy-27-oxido-2,8,14,20-tetra-thia-calix[4]arene: a mol-ecular salt

摘要

In the title mol-ecular salt, C8H20N+·C44H53O6S4?, the conformation of the anionic tetra-thia-calix[4]arene, which is cone-shaped, is primarily determined by intra-molecular O—H?O hydrogen bonds. There are also short intra-molecular C— H?O contacts present. The guest species do not sit within the bowl of the calixarene. One of the?t-butyl groups in the anion is disordered over two sets of sites with refined occupancies of 0.706?(6) and 0.294?(6). Atoms of both cations are equally disordered over centers of symmetry. In the crystal, extensive O—H?O and C—H?O hydrogen bonds and weak O—H?S inter-actions link the thia-calixarene anions and tetra-ethyl-ammonium cations, forming a three-dimensional network.
