چکیده
The title compound, C(14)H(10)F(3)NO(3), was prepared by a palladium-catalysed Suzuki-Miyaura coupling reaction. The dihedral angle between the nitro group and its parent benzene ring is 66.85 (19)° while the dihedral angle between the two benzene rings is 49.98 (9)°. The CF(3) group is disordered over two sets of sites with occupancies of 0.457 (8) and 0.543 (8).

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 phe...
