5,11,17,23-Tetra-tert-butyl-25,26,27,28-tetrakis(2-cyanobenzyloxy)-2,8,14,20-tetrathiacalix[4]arene-dichloromethane (1/2).
A new p-tert-butylthiacalix[4]arene derivative, C(72)H(68)N(4)O(4)S(4) x 2CH(2)Cl(2), has been synthesized and is comprised of one tetra-p-tert-butyltetrakis(2-cyanobenzyloxy)tetrathiacalix[4]arene and two dichloromethane molecules. The calix[4]arene molecule is centrosymmetric and adopts an unusual 1,2-alternate conformation via pi-pi interactions between adjacent cyanophenyl rings on the lower rim of the parent thiacalix[4]arene system.
