In the title compound, C(10)H(18)O(5)·H(2)O, the fucopyran-oside ring adopts a chair conformation. The crystal packing is stabilized by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds together with intra-molecular O⋯O [2.2936 (8) Å] and inter-molecular O⋯O [2.7140 (8)-2.829 (3) Å] short contacts. The mol-ecules are linked together to form an infinite chain along the a axis. This structure has been solved previously but with no R-values [Spiers (1931). Z. Kristallogr. Kristallgeom. Kristallphys. Kristallchem.78, 101].
在标题化合物C₁₀H₁₈O₅·H₂O中，岩藻糖吡喃糖苷环呈椅式构象。晶体堆积通过分子间的O—H⋯O和C—H⋯O氢键以及分子内的O⋯O [2.2936 (8) Å]和分子间的O⋯O [2.7140 (8) - 2.829 (3) Å]短接触得以稳定。分子沿a轴连接在一起形成无限链。该结构先前已被解析，但未给出R值[斯皮尔斯（1931年）。《晶体学报。晶体几何学。晶体物理学。晶体化学》78, 101] 。
