Abstract
The crystal structure of 15,17-di-2-propenylcalix[4]arene-25,26,27,28-tetrol [systematic name: 15,17-di-2-propenylpentacyclo[19.3.1.13,7.19,13.115,19]octacosa-1(25), 3,5,7(26),9,11,13 (27),15,17,19 (28),21,23-dodecaene-25,26,27,28-tetrol], C34H32O4, was determined. The calix[4]arene molecule shows a cone conformation, stabilized by a ring-like hydrogen-bond pattern of the four hydroxyl H atoms. In the crystal structure, complexation of one of the propenyl side chains in the cavity of another calixarene molecule is found. The other side chain shows C—H⋯O interactions with a neighbouring calixarene molecule.
