The title compound, C15H13NO2, was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the biphenyl rings is 40.96 (6)°. The methoxy groups are twisted slightly out of the plane of the benzene ring [C-C-C-C torsion angles = -3.61 (18) and 12.6 (2)°]. The packing of the molecules is stabilized by van der Waals interactions.

The title compound, C14H13NO4, was prepared through a palladium-catalysed Suzuki-Miyaura coupling reaction. The asymmetric unit comprises two molecules related by pseudo-inversion symmetry. The dihedral angles between the benzene rings in the two molecules are 44.30 (6) and 48.50 (6)° while those between the benzene ring and the nitro group are 6.54 (13) and 5.73 (10)°. The crystal packing is defined only by Van der Waals interactions.
