Projection of the structure of compound 4 parallel to the a axis. Molecules 2 are indicated by the thicker bonds of the rings. Thick dashed lines indicate Br⋯Br contacts between the double chains of molecule 1 and 2 (in the regions y ≃ 0.5, z ≃ 0 and y ≃ 0.5, z ≃ 0.5 respectively, and in regions related to these by symmetry). Thin dashed lines are contacts within the chains, as seen in the previous two figures.
