Figure 7
Part of the crystal structure of (2), showing one of the R¹²₁₄(48) rings bounding the cavities in the anion/water framework. For the sake of clarity H atoms bonded to C are omitted. Atoms marked with a star (*), hash (#), dollar ($), at (@) or ampersand (&) signs are at the symmetry positions 1 + x, y, z; $[x, {1\over 2} - y, {1\over 2} + z]$ ; $[1 - x, {1\over 2} + y, {3\over 2} - z]$ ; $[1 + x, {1\over 2} - y]$ , $[-{1\over 2} + z]$ ; $[-x, {1\over 2} + y, {3\over 2} - z]$ , respectively.
