(Received 19 November 2009; accepted 23 November 2009; online 28 November 2009)

In the title salt, C21H18ClNO, the quinoline ring system is approximately planar [maximum deviation = 0.035 (2) Å], and forms a dihedral angle of 71.42 (6)° with the attached phenyl ring. The cyclo­hexa­none ring exists in a half-boat conformation. In the crystal packing, C—H⋯O contacts link the mol­ecules into extended supra­molecular chains along the c axis.

Comment top

Quinolines and their derivatives are very important compounds because of their wide occurrence in natural products (Morimoto et al., 1991; Michael, 1997) and biologically active compounds (Markees et al., 1970; Campbell et al., 1988). A large variety of quinolines have interesting physiological activities and have found attractive applications as pharmaceuticals, agrochemicals and as synthetic building blocks (Maguire et al., 1994; Kalluraya & Sreenivasa, 1998; Roma et al., 2000; Chen et al., 2001). Because of their great importance, the synthesis of new derivatives of quinoline remains an active research area. Recently, we have reported the synthesis of some novel quinoline derivatives (Fun, Loh et al., 2009; Fun, Yeap et al., 2009).

In the title compound (Fig. 1), the quinoline ring system (C1–C8/C13/N1) is approximately planar with a maximum deviation of 0.035 (2) Å at atom C13. The mean plane through the quinoline ring forms a dihedral angle of 71.42 (6)° with the phenyl ring (C14–C19). The cyclohexanone (C8–C13) ring exists in a half-boat conformation. The puckering parameters (Cremer & Pople, 1975) are Q = 0.5017 (17) Å; Θ = 126.65 (18)° and ϕ = 352.8 (2)°. Bond lengths and angles are comparable to that in a closely related structure (Loh et al., 2009).

In the crystal packing (Fig. 2), C3—H3···O1 (Table 1) hydrogen bonds link neighbouring molecules, forming extended one-dimensional chains along c axis.

Experimental top

A 1:1 mixture of 2-amino-5-chlorobenzophenone (0.2 g, 0.001 M), 5,5-dimethyl-1,3-cyclohexanedione (0.14 g, 0.001 M), and 1.0 ml concentrated HCl in distilled ethanol was irradiated for about 12 min under microwave irradiation at 240 W in a domestic microwave oven. The resulting mixture was poured on to ice and neutralized. The solid that formed was filtered, dried and purified by column chromatography using a 1:1 mixture of chloroform and petroleum ether. M. pt.: 459–461 K, yield: 45%.

Refinement top

All hydrogen atoms were located from the difference Fourier map and were refined freely [range of C–H = 0.936 (19) to 1.020 (2) Å].

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.
