Figure 14
Part of the crystal structure of (4), showing the linking of the (100) sheets by the type 2 cations. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($), an ampersand (&) or an at sign (@) are at the symmetry positions (−x, 1 − y, −z), (x, − y, + z), (x, y, 1 + z), (−x, 1 − y, 1 − z) and (−x, − + y, − z), respectively. |
