Figure 12
Part of the crystal structure of (5), showing the formation of a molecular ladder along [100]. For the sake of clarity, H atoms not involved in the hydrogen bonding are omitted. The atoms marked with a star (*), hash (#), dollar sign ($), ampersand (&) or at sign (@) are at the symmetry positions (−1 + x, y, z), (1 + x, y, z), (1 − x, 1 − y, 1 − z), (2 − x, 1 − y, 1 − z) and (−x, 1 − y, 1 − z), respectively. |
