Figure 14
Part of the crystal structure of (6), showing the formation of a (001) sheet by the hard hydrogen bonds. For the sake of clarity, H atoms bonded to C are omitted. The atoms marked with a star (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions (1 + x, y, z), (1 − x, − + y, − z), (2 − x, − + y, − z) and (2 − x, + y, − z), respectively. |
