Figure 2
A view of the mol­ecular packing of 1 along the helical b-axis showing the association of closely linked mol­ecules by C=O⋯C≡C (acetyl­ene, C=O⋯π) and marginal C—H⋯π (π-cloud of acetyl­ene mol­ecules) contacts. Neighbouring helices along the longer c axis are linked by C—H⋯Br contacts. Symmetry codes as in Table 1[link].
