Figure 7
Part of the crystal structure of compound (III), showing the formation of a hydrogen-bonded C(7) chain running parallel to the [001] direction. For the sake of clarity, the H atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions (x, −y + , z + ) and (x, −y + , z + ), respectively. |
