Figure 5
A packing diagram for polymorph (Ia), viewed parallel to the a axis. H atoms have been omitted. Br⋯Br interactions indicated by thin dashed lines correspond to those shown in Fig. 4, while those indicated by thick dashed lines and numbered (1 and 6) do not appear in Fig. 4. One representative Br⋯π interaction is represented by `π'. Labelled Br atoms belong to the asymmetric unit and the labels refer to atoms nearer the viewer. |
