Abstract

The crystal structure of β-cyclo­dextrin, C42H70O35·10.41H2O, consists of truncated cone-shaped β-cyclo­dextrin mol­ecules that are herringbone packed. The primary hydr­oxy groups form an intra­molecular hydrogen-bonded array. The semipolar cavity of the cyclo­dextrin host is filled with water mol­ecules, which show partial occupancy and disorder.

Highlights
