Figure 2 A portion of the crystal structure of (I) showing the positions of K+ [symmetry code: (A) 1 - x,-y, z; (B) [{1\over 2}] + x,1/2 - y, -z; (C) x,y, -1 + z; (D) -[{1\over 2}] + x,1/2 - y, 1 - z; (E) [{3\over 2}] - x,-[{1\over 2}] + y,1 - z; (F) [{3\over 2}] - x,1/2 + y, 1 - z; (G) x,-1 + y, z; (H) 1 - x,-y,-1 + z; (I) -[{1\over 2}] + x,-[{1\over 2}] - y,1 - z; (J) -[{1\over 2}] + x,1/2 - y,-z]. O6 belongs to the water molecule. H atoms omitted for clarity.  [article HTML]
