Figure 2
Part of the crystal structure of (1), showing the formation of a chain of fused rings along [010]. For the sake of clarity, H atoms bonded to C are omitted. The atoms marked with a star (*), hash (#) or dollar sign ($) are at the symmetry positions (x, −1 + y, z), ( − x, + y, − z) and ( − x, − + y, − z), respectively. |
