An N—H⋯Cl hydrogen bond connects the ions in the title salt, C18H16NO+·Cl−. The quinolin-1-ium residue is almost planar (r.m.s. deviation = 0.020 Å) but both the acetyl group [O—C—C—C torsion angle = 62.73 (17)°] and adjacent benzene ring [C—C—C—C torsion angle = −104.06 (14)°] are twisted out of this plane; the acetyl and benzene substituents are non-parallel [dihedral angle = 66.16 (7)°]. The crystal packing is consolidated by C—H⋯O and C—H⋯Cl contacts.

A mixture of 2-aminobenzophenone (0.01 M), acetylacetone (0.01 M) and a catalytic amount of conc. HCl was irradiated under 240 W for about 5 min. The resultant solid was filtered, dried and purified by
using a 1:1 mixture of ethyl acetate and petroleum ether, and recrystallized using ethanol. M.pt. 371–373 K. Yield: 65%.Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 to 0.98 Å) and were included in the
in the riding model approximation, with Uiso(H) set to 1.2 to 1.5Uequiv(C). The pyridinium-H atom was refined with the distance restraint N–H = 0.88±0.1 Å, and with Uiso(H) = 1.2Uequiv(N).The potential pharmacological properties of quinoline derivatives (Musiol et al., 2006) motivate our studies into the structural chemistry of such derivatives (Kaiser et al., 2009; Viji et al., 2010). Herein, the crystal and molecular structure of the title salt is described.
The
comprises a 3-acetyl-2-methyl-4-phenylquinolin-1-ium cation and a chloride anion, being connected by a N–H···Cl hydrogen bond, Fig. 1 and Table 1. The non-hydrogen atoms comprising the quinolin-1-ium residue are planar with a r.m.s. deviation of 0.020 Å. The acetyl group at C3 and the adjacent benzene ring are twisted out of the plane of the quinolin-1-ium residue as seen in the values of the O1–C2–C3–C4 and C10–C11–C13–C14 torsion angles of 62.73 (17) and -104.06 (14) °, respectively. The acetyl and benzene substituents are splayed as seen in the dihedral angle formed between them of 66.16 (7) °.In addition to the N–H···Cl hydrogen bond, the
features C–H···O and C–H···Cl contacts. The former lead to supramolecular chains along the b axis and these are consolidated in three-dimensions by the C–H···Cl contacts, Fig. 2 and Table 1.For background to the pharmaceutical potential of quinoline derivatives, see: Musiol et al. (2006). For related structures, see: Kaiser et al. (2009); Viji et al. (2010).

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. |

The potential pharmacological properties of quinoline derivatives (Musiol et al., 2006) motivate our studies into the structural chemistry of such derivatives (Kaiser et al., 2009; Viji et al., 2010). Herein, the crystal and molecular structure of the title salt is described.
The asymmetric unit comprises a 3-acetyl-2-methyl-4-phenylquinolin-1-ium cation and a chloride anion, being connected by a N–H···Cl hydrogen bond, Fig. 1 and Table 1. The non-hydrogen atoms comprising the quinolin-1-ium residue are planar with a r.m.s. deviation of 0.020 Å. The acetyl group at C3 and the adjacent benzene ring are twisted out of the plane of the quinolin-1-ium residue as seen in the values of the O1–C2–C3–C4 and C10–C11–C13–C14 torsion angles of 62.73 (17) and -104.06 (14) °, respectively. The acetyl and benzene substituents are splayed as seen in the dihedral angle formed between them of 66.16 (7) °.
In addition to the N–H···Cl hydrogen bond, the crystal structure features C–H···O and C–H···Cl contacts. The former lead to supramolecular chains along the b axis and these are consolidated in three-dimensions by the C–H···Cl contacts, Fig. 2 and Table 1.
