Description
Summary:Lactitol dihydrate, C 12H 24O 11·2H 2O, is tetragonal, space group P4 32 12 with cell dimensions a and b = 8.762(1), c = 45.500(3) Å, and V = 3493.2(3) Å 3; Z = 8, D x = 1.45 Mg.m −3, λ(Cu- K α) = 1.54056 Å, μ = 1.108 mm −1, F(000) = 1632, and T = 23°. The structure was solved by direct methods and refined by least-squares calculations to R = 0.054 for 2037 unique observed reflections. There are three intra- and twelve inter-molecular hydrogen bonds in the structure. Bond lengths and angles accord quite well with the mean values of related structures. The galactopyranosyl ring has a chair of conformation.
