Figure 3
Part of the crystal structure of (I), showing the formation of the type 2 chain of rings. For clarity, H atoms bonded to C atoms and the unit-cell box have been omitted. Atoms marked with an asterisk (*), a hash (#) or an ampersand (&) are at the symmetry positions (1 − x, − + y, − z), (1 − x, + y, − z) and (x, 1 + y, z), respectively. |
