Abstract: The title compound, C13H10N2O4, was synthesized as an intermediate 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 molecules are linked into one-dimensional chains by N-H
O hydrogen bonds along the b axis. Weak interactions between O atoms of the nitro groups (O
O = 3.012 Å) connect two adjacent chains.
