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.
摘要
标题化合物C₁₃H₁₀N₂O₄被合成为制备脲的中间体。两个芳环围绕中心氨基甲酸酯基团扭转，C-C-N-C扭转角为139.6(2)°，C-C-O-C扭转角为95.9(2)°。分子通过沿b轴的N-H⋯O氢键连接成一维链。硝基的O原子之间的弱相互作用（O⋯O = 3.012 Å）连接相邻的两条链。
