Figure 4
A packing diagram for polymorph (Ia), viewed perpendicular to (01). H atoms have been omitted. Br⋯Br interactions are indicated by dashed lines and are numbered according to Table 2; contact 4 lies behind contact 7. One representative C(—H)⋯Br interaction is represented by a dotted line (top right). Labelled Br atoms belong to the asymmetric unit and Br1 lies behind Br2. |
