Figure 3
Part of the structure of (I) showing the linking of adjacent (001) sheets into a bilayer. For the sake of clarity, H atoms bonded to C atoms and to atoms C12 and C16 of the anion have been omitted. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions ( − x, ½ + y, z), (x, 1 + y, z), (1 − x, 1 − y, 1 − z) and (−½ + x, ½ − y, 1 − z), respectively. |
