Figure 7
(a) The C(8) hydrogen-bonded chains of (VI)[link] connected by Br⋯O halogen bonds to form two-dimensional sheets. (b) The sheets form bilayers through further Br⋯Br halogen bonding. Atoms marked with the superscripts `i', `ii' and `iii' are at the symmetry positions (x − 1, y, z − 1), (x + 1, y, z) and (−x + 2, −y, −z + 2), respectively. H atoms not involved in hydrogen-bonding inter­actions have been omitted for clarity.
