In the title compound, C(12)H(15)NO(7)·0.5H(2)O, there are two independent mol-ecules in the asymmetric unit, together with one water molecule. The pyran-oside rings each have close to a (1)C(4) chair conformation and the nitro groups are almost coplanar with the benzene rings. The water mol-ecule links the two independent mol-ecules through O-H⋯O hydrogen bonds. All the hydroxyl groups are involved in hydrogen-bond inter-actions, giving rise to a three-dimensional network.
在标题化合物C₁₂H₁₅NO₇·0.5H₂O中，不对称单元中有两个独立分子以及一个水分子。吡喃糖苷环各自具有接近(1)C₄椅式构象，硝基几乎与苯环共面。水分子通过O—H⋯O氢键连接两个独立分子。所有羟基都参与氢键相互作用，形成三维网络。
