(E)-1-(6-Chloro-2-methyl-4-phenyl-3-quinol-yl)-3-(2-methoxy-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C(26)H(20)ClNO(2), the quinoline ring system and the methoxy-phenyl ring form dihedral angles of 69.97?(6) and 22.10?(10)°, respectively, with the propenone linkage. The 4-phenyl ring substituent on the quinoline ring system is oriented at a dihedral angle of 66.47?(3)°. In the crystal, mol-ecules exist as C-H?O hydrogen-bonded dimers. The structure is further stabilized by C-H?? inter-actions.

Project description:In the title compound, C(27)H(22)ClNO(2), the phenyl substituent on the quinoline ring system is almost perpendicular to it [dihedral angle = 88.2?(1)°]. The quinoline ring system and the ethoxy-phenyl 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 mol-ecules exist as C-H?O hydrogen-bonded R(2) (2)(8) dimers.

1-(6-Chloro-2-methyl-4-phenyl-quinolin-3-yl)-3-(3-methoxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(26)H(20)ClNO(2), 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(2) (2)(8) ring motif. The structure is further stabilized by C-H?? inter-actions.

Project description:The title mol-ecule, C(16)H(13)ClO(2), is trans with respect to the C=C double bond. The dihedral angles between the mean plane of the prop-2-en-1-one unit and those of the 3-chloro- and 4-meth-oxy-substituted benzene rings are 20.93?(9) and 20.42?(10)°, respectively, and the dihedral angle between the mean planes of the two benzene rings is 40.96?(5)°. The crystal structure is stabilized by weak inter-molecular C-H?O hydrogen bonds, forming chains along the b axis.

(E)-3-(2-Chloro-phen-yl)-1-(3-methoxy-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(16)H(13)ClO(2), adopts an E configuration with respect to the double bond of the propenone unit. The two benzene rings are twisted slightly from each other, making a dihedral angle of 7.14 (5)°.

Project description:The crystal structure of the title compound, C(25)H(18)ClNO, shows that the mol-ecules are isolated and not involved in inter-molecular C-H⋯O or C-H⋯Cl inter-actions. However, the phenyl and quinoline rings are involved in π-π inter-actions [centroid-centroid distance = 3.8829 (9) Å].

(2E)-1-(6-Chloro-2-methyl-4-phenyl-quinolin-3-yl)-3-(4-chloro-phen-yl)prop-2-en-1-one.

Project description:Two independent mol-ecules comprise the asymmetric unit of the title chalcone, C(25)H(17)Cl(2)NO, and while each has an E configuration about the ethyl-ene double bond, they differ in the relative orientations of the carbonyl and ethyl-ene double bonds within the prop-2-en-1-one residues, i.e. anti and syn. For each mol-ecule, the benzene [dihedral angles = 71.04 (9) and 73.34 (12)°] and prop-2-en-1-one [C-C-C-O = 91.2 (2) and -119.1 (3)°] substituents are twisted out of the plane of the quinoline moiety to which they are attached. The crystal structure is stabilized by C-H⋯π and π-π [Cg(quinoline)⋯Cg(quinoline) = 3.7809 (12) and 3.8446 (11) Å] inter-actions.

Project description:In the title mol-ecule, C(23)H(16)ClNO, the quinoline and naphthalene ring systems are individually planar, with maximum deviations of 0.020?(2) and 0.033?(2)?Å, respectively, and are inclined at a dihedral angle of 30.01?(4)°.
