Abstract: In the title compound, C₁₂H₁₅NO₇·0.5H₂O, there are two independent molecules in the asymmetric unit, together with one water molecule. The pyranoside rings each have close to a ¹C₄ chair conformation and the nitro groups are almost coplanar with the benzene rings. The water molecule links the two independent molecules through O-HO hydrogen bonds. All the hydroxyl groups are involved in hydrogen-bond interactions, giving rise to a three-dimensional network.
