Figure 19
Part of the crystal structure of compound (VIII) showing the formation of a C(7) chain of anions, parallel to [10]. Hydrogen bonds are drawn as dashed lines and, for the sake of clarity, the H atoms bonded to C atoms have been omitted. The atoms marked with an asterisk (*) or a hash (#) are at the symmetry positions ( + x, − y, −1 + z) and (− + x, − y, 1 + z), respectively. |
