Figure 7
Part of the crystal structure of compound (III), showing the formation of a hydrogen-bonded C(6) chain along [010]. 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 (x, 1 + y, z), respectively. |
