Abstract: The host molecule in the title compound, cyclohexakis[(14)-3-deoxy--D-arabino-hexopyranosyl] n-butanol hexahydrate, C₃₆H₆₀O₂₄·C₄H₁₀O·6H₂O, has a cavity similar in diameter but smaller in torus height than that of -cyclodextrin, due to the axial C-2-hydroxyl groups pointing away from the ring plane. The molecules have approximate C₆ symmetry and pack into stacks with channels occupied by disordered n-butanol molecules. Water of srystallization fills the space between the stacks. The structure was determined at 211  K.
