Abstract
The crystal structure of methyl β-D-hamameloside has been determined by direct methods. The trigonal crystals have the space groupR3. Referred to hexagonal axes, there are nine molecules in the non-primitive unit cell witha =b = 18·08(2),c = 7·22(2)Å. The molecule exists in the 1C-trans-chair conformation, with the mean C-C and C-O bond lengths being 1·531 and 1·428Å respectively. The mean value for the carbon bond angle is 110·2 °. The crystal structure is composed of columns of molecules hydrogen-bonded about 32 axes, and with van der Waals forces holding these columns together around the 31 and 3-fold axes.
