Figure 23
Layer structure of 19b viewed perpendicular to (10). Dashed lines indicate short Br⋯Br contacts (thick) or rather longer S⋯Br contacts (thin). The anions based on Au2 are viewed edge-on, so that the atom Au2 is obscured by Br4. The corresponding anion at the right-hand edge of the cell is shown more clearly. The probable hydrogen bonds H3⋯Br3 (see text and Fig. 10) are omitted for clarity. |
