(Received 4 January 2010; accepted 11 January 2010; online 16 January 2010)

In the title compound, C27H22ClNO2, the phenyl substituent on the quinoline ring system is almost perpendicular to it [dihedral angle = 88.2 (1)°]. The quinoline ring system and the ethoxy­phenyl ring are oriented at dihedral angles of 79.5 (1) and 17.6 (3)°, respectively, with respect to the almost planar [r.m.s. deviation= 0.037 (3) Å] –C(=O)—C=C– linkage. In the crystal, the inversion-related mol­ecules exist as C—H⋯O hydrogen-bonded R22(8) dimers.

Comment top

Chalcones are open chain flavonoids possessing a variety of biological activities such as antioxidant, anti-inflammation, antimicrobial, antiprotozoal, antiulcer, as well as other activities (Dimmock et al., 1999). More importantly, chalcones have shown several anticancer activities as inhibitors of cancer cell proliferation, carcinogenesis and metastasis (Zi & Simoneau, 2005; Yamazaki et al., 2002). We report here the crystal structure of the title chalcone derivative.

In the title molecule (Fig. 1), the quinoline ring system (C1/N1/C2–C9) is essentially planar with a maximum deviation of 0.026 (2) Å for atom C2. The C10–C15 and C19–C24 rings form dihedral angles of 88.2 (1)° and 67.8 (1)°, respectively, with the quinoline ring system. The ethoxy group is almost coplanar with the attached ring [C26—O2—C22—C23 = 1.8 (4)° and C22—O2—C26—C27 = -171.7 (3)°]. Bond lengths (Allen et al., 1987) and angles show normal values.

In the crystal packing (Fig. 2), pairs of intermolecular C21—H21A···O2 hydrogen bonds (Table 1) form dimers with neighbouring molecules, generating R22(8) ring motifs (Bernstein et al., 1995). The dimers are stacked down the c axis (Fig. 2).

Experimental top

A mixture of 3-acetyl-6-chloro-2-methyl-4-phenylquinoline (2.95 g, 0.01 mmol), 4-ethoxybenzaldehyde (1.50 g, 0.01 mmol) and a catalytic amount of KOH in distilled ethanol was stirred for 12 h. The resulting mixture was concentrated to remove the ethanol and then poured onto ice and neutralized with diluted acetic acid. The resultant solid was filtered, dried and purified by column chromatography using a 1:1 mixture of ethylacetate and petroleum ether (m.p 401–403 K).

Refinement top

H atoms were positioned geometrically [C–H = 0.93–0.97 Å] and refined using a riding model, with Uiso(H) = 1.2-1.5Ueq(C). A rotating group model was used for the methyl groups. The ratio of observed to unique reflections is low (36%), and the value of Rint is greater than 0.10, probably due to the poor diffraction quality of the crystal.

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'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 > σ(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.
