Figure 8
Part of the crystal structure of compound (III), showing the formation of a hydrogen-bonded chain of cations along [010]. Hydrogen bonds are drawn as dashed lines and, for the sake of clarity, the unit-cell outline, the minor disorder components and the H atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( − x, − + y, − z) and ( − x, + y, − z), respectively. |
