4-Fluoro-N-(4-hy-droxy-benzyl-idene)aniline

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.
