Two independent molecules comprise the 25H17Cl2NO, and while each has an E configuration about the ethylene double bond, they differ in the relative orientations of the carbonyl and ethylene double bonds within the prop-2-en-1-one residues, i.e. anti and syn. For each molecule, the benzene [dihedral angles = 71.04 (9) and 73.34 (12)°] and prop-2-en-1-one [C—C—C—O = 91.2 (2) and −119.1 (3)°] substituents are twisted out of the plane of the quinoline moiety to which they are attached. The is stabilized by C—H⋯π and π–π [Cg(quinoline)⋯Cg(quinoline) = 3.7809 (12) and 3.8446 (11) Å] interactions.

A mixture of 3-acetyl-6-chloro-2-methyl-4-phenylquinoline (3.1 g, 0.01 M) and 4-chlorobenzaldehyde (1.4 g, 0.01 M) and a catalytic amount of KOH in distilled ethanol (40 ml) was stirred for about 12 h. The resulting mixture was concentrated to remove ethanol, poured onto ice and neutralized with dilute acetic acid. The resultant solid was filtered, dried and purified by
using a 1:1 mixture of ethyl acetate and petroleum ether. Recrystallization was from acetone; Yield: 64% and m.pt: 397–399 K.Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.96 Å) and were included in the
in the riding model approximation, with Uiso(H) set to 1.2 to 1.5Uequiv(C).Data collection: CrysAlis PRO (Agilent, 2010); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Chalcones and its analogs are valuable intermediates in organic synthesis and exhibit a multitude of biological activities. From a chemical point of view, an important feature of chalcones and their heteroanalogs is the ability to act as activated unsaturated systems in conjugated addition reactions of carbanions in the presence of basic catalysts (Roman, 2004). The title compound, (I), was examined in continuation of our interest in the structural chemistry of chalcones (Prasath et al., 2010; Reddy et al., 2010).
Two independent molecules comprise the asymmetric unit of (I), one with an anti relationship between the carbonyl and ethylene double bonds, Fig. 1, and one with a syn relationship, Fig. 2. In each, the conformation about the ethylene bond [C18═C19 = 1.319 (3) Å and C43═C44 = 1.328 (3) Å] is E. For both molecules, the benzene ring is twisted out of the plane of the quinoline residue to which it is connected; the C6—C7—C11—C12 and C31—C32—C36—C37 torsion angles are -69.0 (2) and -107.1 (2) °, respectively. The prop-2-en-1-one substituents are also twisted out of the plane of the respective quinoline residues as seen in the values of the C7—C8—C17—O1 and C32—C33—C42—O2 torsion angles of 91.2 (2) and -119.1 (3) °, respectively. Within the prop-2-en-1-one substituents themselves, the terminal benzene rings are not co-planar with the C18—C19—C20—C21 and C43—C44—C45—C46 torsion angles being -159.6 (2) and -170.8 (2) °, respectively.
The molecules are stabilized in the crystal packing by a combination of C—H···π, π–π, and C—Cl···π interactions. The C—H···π contacts, Table 1, occur between the two molecules comprising the asymmetric unit. The π–π interactions occur between centrosymmetrically related quinoline rings belonging to like molecules [Cg(N1,C1,C6—C9)···Cg(C1—C6)ii = 3.8446 (11) ° for ii: 1 - x, 1 - y, -z; and Cg(N2,C26,C31—C34)···Cg(C26—C31)iii = 3.7809 (12) ° for iii: 1 - x, 1 - y, 1 - z]. The C—H···Cl contacts [C4—Cl1···Cg(C20—C25)iv = 3.6082 (13) Å and angle at Cl1 = 116.34 (7) ° for iv: -1 + x, y, z] also occur between like molecules. A view of the crystal packing is shown in Fig. 3.
