Figure 20
Packing diagram of 20a. The viewing direction has been rotated by ca 20° and 10° respectively around the horizontal and vertical directions from the direction parallel to the b axis (to avoid overlap of the two S⋯Cl contacts). Hydrogen atoms are omitted for clarity. Dashed lines indicate Cl⋯Cl and S⋯Cl contacts. The unusual orientation of the tetrachloroaurate(III) anion at Au1, with an approximately synperiplanar grouping Cl1⋯Cl2—Au1—Cl3, can be recognized. |
