چکیده
In the title compound, C(20)H(15)F(2)NO, the mean plane of the acetamide group makes dihedral angles of 88.26 (6), 78.30 (7) and 9.83 (6)° with the two terminal benzene rings and difluoro-substituted benzene ring, respectively. One F atom is disordered over two orientations rotated by 180°, with a site-occupancy ratio of 0.557 (2):0.443 (2). An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds into chains along the c axis. The crystal structure is further consolidated by C-H⋯π inter-actions.

In the title compound, C(14)H(13)NO, which has two mol-ecules in the asymmetric unit, the dihedral angles between the mean planes of the benzene rings are 84.6 (7) and 85.0 (6)°. N-H⋯O hydrogen bonds [forming R(2) (2)(8) ring motifs] and C-H⋯O hydrogen bonds dominate the crystal packing, forming zigzag chains parallel to the a axis. In addition, weak inter-molecular C-H⋯π inter-actions are obse...

In the title amide, C(16)H(15)F(2)NO(3), the dihedral angle between the benzene rings is 53.7 (1)°. Mol-ecules are linked in the crystal structure by an inter-molecular N-H⋯O hydrogen bond involving N-H and C=O functionalities of the amide group. A one-dimensional network is thus formed along the [001] direction. No significant inter-chain contacts are observed.
