ABSTRACT
In the title mol-ecule {systematic name: (5S)-5-[(ß-d-gluco-pyranos-yloxy)meth-yl]furan-2(5H)-one}, C(11)H(16)O(8), the five-membered ring is essentially planar, the maximum deviation being 0.0151â (13)â Å for the O atom. The six-membered ring adopts a chair conformation with puckering parameters Q = 0.581â (2)â Å, θ = 9.0â (2)° and Ï = 39.7â (13)°, and with all of the substituents of the glucoside unit having normal equatorial orientations. The crystal structure is stabilized by extensive O-Hâ¯O and C-Hâ¯O hydrogen bonding, resulting in a three-dimensional network.
