甲基ED-吡喃葡萄糖苷C7H1406的晶体结构已通过对HKO投影数据的符号相关程序和对三维E_2-1-1 Patterson合成的检查而确定。空间群为P212121，四个分子分别位于a=11.304_+0.010，b=14.785_+0.015和c=5.282_0的晶胞中。005/易。该分子为反式C1椅构象。CC或C-OH键的长度与其各自的平均值均无显著差异。C(1)-O(1)键略有缩短，吡喃糖环上的碳氧键长度有显著差异。
The crystal structure of methyl eD-glucopyranoside, C7H1406, has been determined by application of the sign correlation procedure to the hkO projection data and by inspection of the three-dimensional E2--1 Patterson synthesis. The space group is P212121, with four molecules in a unit cell of dimensions a= 11.304 _+ 0.010, b= 14.785 _+ 0.015 and c= 5.282 _0. 005/Yi. The molecule is in the trans C1 chair conformation. None of the CC or C-OH bond lengths differ significantly from their respective means. The C (1)-O (1) bond is slightly shortened and there is a significant difference between the carbon oxygen bond lengths in the pyranose ring.
