摘要：

The crystals of di-.beta.-D-fructofuranose 2'',1:2,3''-dianhydride are monoclinic, space group P21, with unit-cell dimensions a = 12.8557(14), b = 7.7266(7), c = 7.0322(9).ANG., .beta. = 97.395(10).degree., z = 2. The structure was solved by the direct method, and refined to an R value of 0.046 and an Rw value of 0.048 for 2123 observed reflections. The conformations of the furanose rings are 2E with P = 302.5.degree. and .tau.m = 39.4.degree. for D-fructose 1, and 3T2 with P = 145.7.degree. and .tau.m = 35.8.degree. for D-fructose 2. The fused, 1,4-dioxane ring has a chair conformation with Cremer-Pople puckering parameters Q = 0.501 .ANG. and .theta. = 8.1.degree.
