title: 4-Bromo-1-nitro-benzene.
abstract: The non-H atoms of the title mol-ecule, C(6)H(4)BrNO(2), are essentially coplanar with an r.m.s. deviation of 0.040 Å. In the crystal, π-π stacking occurs between parallel benzene rings of adjacent mol-ecules with centroid-centroid distances of 3.643 (3) and 3.741 (3) Å. Weak inter-molecular C-H⋯O hydrogen bonding and short Br⋯O contacts [3.227 (4) 3.401 (4) Å] are also observed in the crystal structure. The crystal studied was a non-morohedral twin with a 26.1 (6)% minor component.
