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. |
