Methyl 4,6-O-benzyl-idene-α-d-gluco-pyran-oside monohydrate.

The title compound, C14H18O6·H2O, is a partially protected derivative of d-gluco-pyran-ose. The asymmetric unit contains one sugar molecule and one water molecule of crystallization. Classical hydrogen bonds of the O-H⋯O type form a cooperative set and are observed next to a C-H⋯O(water) contact, connecting the entities of the asymmetric unit into a three-dimensional network.
