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. |
