Figure 3
A detail of (I), showing how C—H⋯π interactions involving atoms H3 and H13 provide coherence between herring-bone-like sheets of molecules. Note also how a Br atom is positioned approximately trans to every C—H⋯π bond (see Comment). H atoms not involved in the interactions shown have been omitted.
