چکیده
In the title compound, C(13)H(8)Br(2)N(2)O(6), the 2-furyl ring is essentially planar, with a maximum deviation of 0.002 (2) Å. It is inclined at an angle of 33.94 (9)° to the benzene ring. Both nitro groups are slightly twisted away from their attached rings; the dihedral angles are 4.6 (2)° between the nitro group and the 2-furyl ring, and 13.72 (19)° between the nitro group and the benzene ring. In the crystal, mol-ecules are linked into chains along [110] and [10] via two pairs of inter-molecular C-H⋯O hydrogen bonds, displaying R(2) (2)(10) ring motifs.
