Figure 12
Part of the crystal structure of (III), showing the formation of a C(4)C(9)[R21(6)] chain of rings along [010]. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (1 − x, + y, − z) and (1 − x, − + y, − z), respectively. |
