Figure 2
Part of the crystal structure of (I), showing the formation of a hydrogen-bonded chain of rings along [001]. For the sake of clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#) or an ampersand (&) are at the symmetry positions (2 − x, 1 − y, + z), (2 − x, 1 − y, − + z) and (x, y, −1 + z), respectively. |
