چکیده
In the title compound, C13H10FNO, the benzene ring planes are inclined at an angle of 50.52 (8)°. A characteristic of aromatic Schiff bases with N-aryl substituents is that the terminal phenyl rings are twisted relative to the plane of the HC=N link between them. In this case, the HC=N unit makes dihedral angles of 10.6 (2) and 40.5 (2)° with the hy-droxy-benzene and fluro-benzene rings, respectively. In the crystal, O-H⋯N and C-H⋯F hydrogen bonds lead to the formation of chains along the c- and b-axis directions, respectively. C-H⋯π contacts link mol-ecules along a and these contacts combine to generate a three-dimensional network with mol-ecules stacked along the b-axis direction.

The title compound, C(19)H(13)F(2)N, was synthesized by an addition reaction of bis-(4-fluoro-phen-yl)methanone with aniline. The dihedral angles formed by the fluoro-benzene rings with the aniline ring are 81.04 (5) and 64.15 (5)°. In the crystal packing, inter-molecular C-H⋯F hydrogen bonds link mol-ecules into zigzag chains parallel to the c axis.

Chlorination of 3-fluoro-2-methyl-aniline with N-chloro-succinimide gave one major regioisomer whose structure was determined by X-ray crystallography. The product was found to have cocrystallized with succinimide, giving the title compound, C(7)H(7)ClFN·C(4)H(5)NO(2). The crystal structure is stabilized by N-H⋯O hydrogen-bonding and π-π stacking inter-actions with a centroid-centroid distance ...
