Figure 9
Part of the crystal structure of compound (III) , showing the formation of a hydrogen-bonded C(6) chain along [1 0]. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( + x, − + y, z) and (− + x, − + y, z), respectively. |
