Figure 1 View of the expanded asymmetric unit of K+.C6H7O9S−.2H2O, showing the conformation of the anion, the coordination of the potassium cation and the locations of the water molecules; all the potassium ions bonded to the anion are included. In all the figures, thermal ellipsoids are drawn at the 50% probability level, and hydrogen atoms are drawn as spheres of arbitrary size. Superscripts in the atom labels denote symmetry operations as defined in the Tables of molecular dimensions and hydrogen bonds. |
