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 cyclo-hexa-none ring exists in a half-boat conformation. In the crystal packing, C - H⋯O contacts link the mol-ecules into extended supra-molecular chains along the c axis.

In the title compound, C26H20ClNO2, the quinoline ring system is approximately planar with a maximum deviation of 0.028 (2) Å and forms a dihedral angle of 73.84 (5)° with the phenyl ring. Two neighbouring mol-ecules are arranged into a centrosymmetric dimer through a pair of inter-molecular C-H⋯Cl inter-actions. A pair of inter-molecular C-H⋯O hydrogen bonds link two methoxy-phenyl groups into another centrosymmetric dimer, generating an R 22(8) ring motif. The structure is further stabilized by C-H⋯π inter-actions.

1-(6-Chloro-2-methyl-4-phenylquinolin-3-yl)-3-(3-methoxyphenyl)prop-2-en-1-one

In the title compound, C27H20ClNO, the quinoline ring forms a dihedral angle of 62.53 (5)° with the substituent benzene ring. In the crystal, inter-molecular C - H⋯Cl inter-actions link the mol-ecules into chains along the b axis. Inter-molecular C - H⋯N and C - H⋯O hydrogen bonds further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible voids, each with a volume of 35 Å3, but no significant electron density was found in them.
