Figure 7
Part of the crystal structure of (II) showing the formation of a (100) sheet built from type 2 molecules only. For the sake of clarity, H atoms bonded to C are omitted. Atoms marked with (*), (#), ($), (&) or (@) are at the symmetry positions (x, −y, − + z), (x, 1 + y, z), (x, −1 − y, + z),(x, −1 − y, − + z) and (x, −y, + z), respectively. |
