The two phenyl rings of the biphenyl unit of the title compound, C(18)H(13)NO(3), are almost coplanar [dihedral angle 6.70 (9)°]. The nitro-phenyl ring, on the other hand, is significantly twisted out of the plane of the these two rings, making dihedral angles of 68.83 (4)° with the middle ring and 62.86 (4)° with the end ring. The nitro group is twisted by 12.1 (2)° out of the plane of the phenyl ring to which it is attached.
标题化合物C(18)H(13)NO(3)的联苯单元的两个苯环几乎共面[二面角6.70 (9)°]。另一方面,硝基苯环明显扭曲出这两个环的平面,与中间环的二面角为68.83 (4)°,与末端环的二面角为62.86 (4)°。硝基相对于其连接的苯环平面扭转了12.1 (2)°。
