Abstract

R factor = 0.042; wR factor = 0.106; data-to-parameter ratio = 8.5. In the title compound, Na + C10H15O3 5H2O, the vertices of a distorted octahedron centred on the Na + cation are defined by six O atoms of water molecules. The edge-sharing Na(H2O)6 octahedra form a chain extended along the b-axis direction with adjacent Na + cations related by a twofold screw symmetry operation. The organic anion, which is not in close contact with the Na + cation, is hydrogen-bonded to an uncoordinated water molecule and to water molecules of the Na(H2O)6 octahedra. Related literature For a crystal structure with similar chains of edge-sharing Na(H2O)6 octahedra, see: Huang et al. (2005).
