Figure 9
Part of the crystal structure of (I), showing the formation of a hydrogen-bonded [010] chain generated by a screw axis. For clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions ( − x, − + y, − z), (x, −1 + y, z) and ( − x, + y, − z), respectively. |
