N-[(E)-4-Chloro-benzyl-idene]-2,4-dimethyl-aniline.

The title mol-ecule, C(15)H(14)ClN, exists in a trans configuration with respect to the C=N bond [1.2813 (16) Å]. The dihedral angle between the benzene rings is 52.91 (6)°. The crystal structure is stabilized by weak inter-molecular C-H⋯π inter-actions.

2-[(E)-(2,4-Dimethyl-phen-yl)imino-meth-yl]phenol.

The asymmetric unit of the title compound, C(15)H(15)NO, contains two independent mol-ecules, both of which exist in trans configurations with respect to the C=N bonds [1.278 (2) and 1.279 (2) Å]. In each mol-ecule, intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. In one mol-ecule, the benzene rings form a dihedral angle of 13.38 (9)°, while in the other mol-ecule the dihedral angle is 30.60 (10)°. In the crystal, the two independent mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonds.

2-[(E)-(2,4,6-Trichloro-phen-yl)imino-meth-yl]phenol.

The title mol-ecule, C(13)H(8)Cl(3)NO, exists in a trans configuration with respect to the C=N bond [1.278 (2) Å]. The benzene rings form a dihedral angle of 24.64 (11)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring motif. In the crystal, π-π stacking inter-actions [centroid-centroid distances = 3.6893 (14) Å] are observed.
