Figure 5
Packing diagram of compound 2a viewed aproximately parallel to the c axis (but rotated by ca 10° about the vertical axis for clarity), showing three chains of molecules parallel to the b axis. The chains are centred on the regions (x, z) = (0, 0), (1, 0) and (1/2, 1/2). Dashed lines indicated Au⋯Br contacts (thick) or Br⋯Br contacts (thin); the latter are shown more clearly in Fig. 6. Atom labels indicate the asymmetric unit. |
