The asymmetric unit of the title compound, C(17)H(19)ClN(2), contains two independent mol-ecules which differ by a 180° flip in the orientation of the 4-chloro-aniline unit with respect to the diethyl-amino-benzyl-idene unit [N=C-C-C = 10.0 (3) and -170.6 (2)°]. The dihedral angles between the two aromatic rings are 64.0 (1) and 66.5 (1)° in the two independent mol-ecules.

In the title compound, C22H16ClNO, the quinoline ring system makes dihedral angles of 56.30 (6) and 7.93 (6)°, respectively, with the adjacent phenyl and benzene rings. The dihedral angle between these phenyl and benzene rings is 56.97 (8)°. In the crystal, weak C-H⋯π and π-π [centroid-centroid distances of 3.7699 (9) and 3.8390 (9) Å] inter-actions link the mol-ecules into a layer parallel to ...

In the title compound, C(14)H(12)ClNO(3)S, the conformation of the N-H bond in the C-SO(2)-NH-C(O) segment is anti to the C=O bond. The mol-ecule is twisted at the S atom with a torsion angle of 69.0 (2)°. The dihedral angle between the sulfonyl benzene ring and the -SO(2)-NH-C-O segment is 77.2 (1)° and that between the sulfonyl and the benzoyl benzene rings is 89.5 (1)°. In the structure, mol...
