Figure 3
A packing diagram for (I), showing part of the one-dimensional hydrogen-bonded ribbon-shaped double-chain network. Atoms labelled with a dollar sign ($), a hash (#) or an ampersand (&) are at the symmetry positions (x – 1, y, z), (x + 1, y, z) and (–x, –y + 1, –z + 1), respectively. H atoms not involved in the hydrogen bonding have been omitted. |
