摘要：

The structure of the title complex, cycloheptaamylose-(Z)-9-dodecen-1-ol-ethanol-water (1/0.5/0.53/9.6), C42H70O35.0.5C(12)H(24)O.9.6H(2)O.0.53C(2)W(6)O, has been determined at 150 K, Two cycloheptaamylose (beta-cyclodextrin, beta-CD) monomers related by a twofold axis form dimers. The stoichiometry of host:guest is 2:1. Therefore, one guest molecule per dimer is enclosed, disordered over two sites related by the above-mentioned twofold axis. The hydrophobic end of the guest lies in the dimeric interface. The rest of the molecular chain transverses the hydrophobic cavity of either monomer and the extreme hydroxy group is found in the primary hydroxy region.
