Figure 2
C—H⋯O and C—H⋯Br (see Table 1 for details) hydrogen bonding (dashed lines) in the title compound, forming a chain of molecules (or ribbon) running down the c axis. Each molecule is related to the next by a centre of inversion. Symmetry codes for the various molecules (and independent unit making up each molecule) are as follows: (i) x, y, z; (ii) −x, y, −z + ; (iii) −x, −y, −z; (iv) x, −y, z − ; (v) −x, −y, −z + 1; (vi) x, −y, z + . |
