Figure 4
Part of the crystal structure of (I), showing the formation of a C(4) hydrogen-bonded chain along [101]. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), a hash (#) or an ampersand (&) are at the symmetry positions ( + x, − y, + z), (− + x, − y, − + z) and (−1 + x, y, −1 + z), respectively. |
