Figure 2
Part of the crystal structure of (I), showing the formation of a chain of edge-fused (11) rings along the b axis. For clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (x, y − 1, z), ( − x, y − , − z), (x, y + 1, z) and ( − x, + y, − z), respectively. |
