Abstract

The asymmetric unit of the title compound, C(8)H(7)Br(2)NO(3), comprises two crystallographically independent mol-ecules (A and B). The nitro groups are twisted from the attached benzene rings, making dihedral angles of 39.26 (9) and 35.90 (9)° in mol-ecules A and B, respectively. In each mol-ecule, the dibromo-methyl group is orientated in such a way that the two Br atoms are tilted away from the benzene ring. An inter-esting features of the crystal structure is the two short Br⋯Br inter-actions which, together with inter-molecular C-H⋯O hydrogen bonds, link the mol-ecules into an extended three-dimensional network. The crystal structure is further stabilized by weak C-H⋯π inter-actions.
