چکیده
Two independent mol-ecules comprise the asymmetric unit of the title compound, C(20)H(16)ClNO, which differ in the orientation of the chalcone residue with respect to the quinoline ring [the C-C-C(=O)-C torsion angles are 69.5 (2) and 86.0 (2)°]. The configuration about each of the ethyl-ene bonds [1.342 (2) and 1.338 (2) Å] is E. The three-dimensional crystal structure is stabilized by a combination of C-H⋯O, C-H⋯N, C-H⋯π inter-actions and π-π contacts between the independent mol-ecules [Cg(C(6) of quinoline)⋯Cg(C(6) of quinoline) = 3.6719 (11) Å].

Two independent but virtually identical mol-ecules comprise the asymmetric unit in the title compound, C(18)H(15)NOS. With reference to the quinolin-3-yl group, the 3-(thio-phen-2-yl)prop-2-en-1-one residue is almost perpendicular, with all but the carbonyl O atom lying to one side of the plane. This conformation is reflected by the C-C-C-C torsion angles of -102.2 (3) and 81.1 (3)° in the two ...
