Abstract

The crystal structure of β-cyclo-dextrin, C(42)H(70)O(35)·10.41H(2)O, consists of truncated cone-shaped β-cyclo-dextrin mol-ecules that are herringbone packed. The primary hydr-oxy groups form an intra-molecular hydrogen-bonded array. The semipolar cavity of the cyclo-dextrin host is filled with water mol-ecules, which show partial occupancy and disorder.

摘要

β-环糊精（C₄₂H₇₀O₃₅·10.41H₂O）的晶体结构由呈人字形堆积的截顶锥形β-环糊精分子组成。伯羟基形成分子内氢键阵列。环糊精主体的半极性空腔中填充有水分子，这些水分子呈现部分占据和无序状态。
