Figure 3
A perspective view of compound (I) , showing intermolecular Br1⋯O interactions as short-dashed lines and intermolecular Br1⋯Br2 interactions as long-dashed lines. The Br⋯O interactions, together with N—H⋯O interactions, form an R33 ring. [Symmetry codes: (i) + x, − y, 2 − z; (ii) − + x, − y, 2 − z; (iii) − x, 1 − y, − + z.] |
