3-Acetyl-2-methyl-4-phenylquinolin-1-ium chloride

Abstract

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.
