Figure 2
A packing diagram for (I), illustrating the layer structure formed via classical hydrogen bonds, C—H⋯O interactions and Br⋯Br contacts (all shown as dashed lines), viewed perpendicular to (102). H atoms not involved in hydrogen bonds have been omitted for clarity. Atom Br2 is at the symmetry position (1 − x, 1 − y, 1 − z), Br4 and C6 are at (1 + x, y, z), Br1, N1 and O1 are at (1 − x, 1 − y, −z), and Br13 is at (−x, 2 − y, −z). Other labelled atoms are those of the asymmetric unit. |
