Figure 9
Part of the crystal structure of (2) showing the formation of a (10) sheet built from four different types of ring. For the sake of clarity, H atoms bonded to C are omitted. Atoms marked with a star (*), hash (#), dollar ($) or at (@) sign are at the symmetry positions (1 - x, -y, -z), (1 - x, -y, 1 - z), (1 + x, 1 + y, z) and (1 + x, 1 + y, 1 + z), respectively. |
