Figure 1
(a) View along [00] onto the cationic water–sodium (100) layer in the crystal structure of Na2SO3(H2O)7 made up from edge- and corner-sharing [Na(H2O)6] octahedra (turquoise). Anisotropic displacement ellipsoids are drawn at the 90% probability level and H atoms are shown as grey spheres of arbitrary radii. Symmetry codes refer to Table 3. (b) The same type of layer in the crystal structure of Na2CO3(H2O)7, with atoms as spheres of arbitrary radii. |
