چکیده
In the title compound, C(16)H(12)BrN(3)O(4), the furan-2(5H)-one ring forms a dihedral angle of 33.19 (9)° with the 4-bromo-benzene unit and is nearly perpendicular to the 4-nitro-benzene segment, making a dihedral angle of 89.93 (10)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules, generating an infinite chain along [010]. The chains are linked into a three-dimensional network by C-H⋯O, C-H⋯π and π-π contacts [centroid-centroid separation = 3.805 (2) Å].
