چکیده
The title compound, C(12)H(7)Br(2)NO(2), a biphenyl derivative, displays a twisted conformation with the two benzene rings making a dihedral angle of 55.34 (14)°. The dihedral angle between the nitro group and its parent benzene ring is 26.8 (2)°. The crystal structure is stabilized by inter-molecular C-H⋯Br and C-H⋯O inter-actions, which lead to the formation of chains propagating along the c-axis direction.
