Figure 7
Part of the crystal structure of (II), showing the formation of a hydrogen-bonded C(5)C(7)[R22(10)] chain of rings parallel to [010]. Dashed lines indicate hydrogen bonds. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash symbol (#) are at the symmetry positions (−x + 1, y + , −z + ) and (−x + 1, y − , −z + ), respectively. |
