Abstract
The title compound, C(13)H(10)N(2)O(4), was synthesized as an inter-mediate for the preparation of ureas. The two aromatic rings are twisted about the central carbamate group with a C-C-N-C torsion angle of 139.6 (2)° and a C-C-O-C torsion angle of 95.9 (2)°. The mol-ecules are linked into one-dimensional chains by N-H⋯O hydrogen bonds along the b axis. Weak inter-actions between O atoms of the nitro groups (O⋯O = 3.012 Å) connect two adjacent chains.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
