Figure 7
Part of the crystal structure of (3), 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 (#) or dollar sign ($) are at the symmetry positions (−1 + x, y, z), (−x, 1 − y, −z) and (−1 − x, 1 − y, −z), respectively. |
