Figure 3
The C(8) hydrogen-bonded chain of (II), showing the Br⋯O halogen-bonded interactions along the [001] direction. The Br⋯Br halogen bonds along the [100] direction are not shown. Atoms marked with the superscripts `i' and `ii' are at the symmetry positions (x − , y + , z) and (x + 1, −y + 1, z + ), respectively. H atoms not involved in hydrogen-bonding interactions have been omitted for clarity. |
