Abstract
In the title compound, C8H6BrNO3, there are two molecules, A and B, in the asymmetric unit. The nitro and ethanone groups lie close to the plane of the benzene ring and the bromine atom is twisted slightly: the dihedral angles between the mean planes of the nitro and ethanone groups and the benzene ring are 4.6 (4) (A) and 2.8 (3) (B), and 0.8 (8) (A) and 5.5 (8)° (B), respectively. An extensive array of weak C—H⋯O hydrogen bonds, π–π ring stacking [centroid–centroid distances = 3.710 (5) and 3.677 (5) Å] and short non-hydrogen Br⋯O and O⋯Br intermolecular interactions [3.16 (6)and 3.06 (8) Å] contribute to the crystal stability, forming a supermolecular three-dimensional network structure along 110. These interactions give rise to a variety of cyclic graph-set motifs and form interconnected sheets in the three-dimensional structure.
