Crystal structure of ethyl 2-chloro-5,8-di-meth-oxy-quinoline-3-carboxyl-ate.

ABSTRACT: In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142?Å) and ester planes is 18.99?(3)°. The C-O-C-Cm (m = meth-yl) torsion angle is -172.08?(10)°, indicating a trans conformation. In the crystal, the mol-ecules are linked by C-H?O and C-H?N inter-actions, generating layers lying parallel to (101). Aromatic ?-? stacking [centroid-centroid distances = 3.557?(2) and 3.703?(2)Å] links the layers into a three-dimensional network.

In the title compound, C14H14ClNO4, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.0142 Å) and ester planes is 18.99 (3)°. The C-O-C-Cm (m = meth-yl) torsion angle is -172.08 (10)°, indicating a trans conformation. In the crystal, the mol-ecules are linked by C-H⋯O and C-H⋯N inter-actions, generating layers lying parallel to (101). Aromatic π-π stacking [centroid-centroid distances = 3.557 (2) and 3.703 (2)Å] links the layers into a three-dimensional network. ...[more]

Project description:In the crystal structure of the title compound, C12H9Cl2NO2, the mean planes through the quinoline and carboxyl-ate groups have r.m.s. deviations of 0.006 and 0.021?Å, respectively, and form a dihedral angle of 87.06?(19)°.

Ethyl 8-meth-oxy-4-oxo-1,4-di-hydro-quinoline-3-carboxyl-ate.

Project description:In the title compound, C13H13NO4, the asymmetric unit contains four independent mol-ecules, each exhibiting an intra-molecular N-H?O hydrogen bond. The ethyl group in one of the four mol-ecules is disordered, with a refined occupancy ratio of 0.295?(16):0.705?(16). A face-to-face stacking inter-action is found between the benzene rings of the quinoline units of two of the mol-ecules [centroid-centroid distance = 3.541?(2)?Å], which are sandwiched by the other two mol-ecules through N-H?O hydrogen bonding. In the crystal, the sandwiched mol-ecules are assembled via stacking inter-actions along the b-axis direction with their translation-symmetry equivalents [centroid-centroid distance = 3.529?(2)?Å], and are further linked through N-H?O hydrogen bonding. The other two mol-ecules are linked via stacking inter-actions with their inversion-symmetry equivalents [centroid-centroid distances = 3.512?(3) and 3.716?(4)?Å] and via N-H?O hydrogen bonding.

Crystal structure of ethyl 2-(2,4,5-tri-meth-oxy-phen-yl)quinoline-4-carboxyl-ate.

Project description:In the title compound, C21H21NO5, the dihedral angle between the quinoline ring system (r.m.s. deviation = 0.028 Å) and the tri-meth-oxy-benzene ring is 43.38 (5)°. The C atoms of the meth-oxy groups deviate from their attached benzene ring by -0.396 (2), -0.049 (2) and 0.192 (2) Å for the ortho-, meta- and para-substituents, respectively. The pendant ethyl chain is disordered over two orientations in a 0.527 (5):0.473 (5) ratio. A short intra-molecular C-H⋯O contact closes an S(6) ring. In the crystal, inversion dimers linked by pairs of weak C-H⋯O inter-actions generate R 2 (2)(6) loops. The dimers are linked by further C-H⋯O inter-actions to generate [1-10] chains.

Crystal structure of ethyl 8-chloro-4-oxo-1,4-di-hydro-quinoline-3-carboxyl-ate.

Project description:In the title compound, C12H10ClNO3, the asymmetric unit comprises two independent mol-ecules, and the dihedral angle between the least-square planes of the quinoline ring systems of these mol-ecules is 73.30 (5)°. In the crystal, N-H⋯O hydrogen bonds between the independent mol-ecules lead to supra-molecular layers parallel to (-1-10); both N-H H atoms are bifurcated.

Crystal structure of 2-chloro-3-(di-meth-oxy-meth-yl)-6-meth-oxy-quinoline.

Project description:The title compound, C13H14ClNO3, crystallizes with Z' = 2 in the space group Pca21, but a search for possible additional crystallographic symmetry found none. However, the crystal structure exhibits pseudosymmetry as the two independent mol-ecules are related by an approximate but non-crystallographic inversion located close to (0.38, 0.26, 1/2) in the selected asymmetric unit, and the structure exhibits partial inversion twinning. The approximate inversion relationship between the two mol-ecules in the selected asymmetric unit is clearly shown by comparison of the relevant torsion angle in the two mol-ecules; the corresponding torsion angles have similar, although not identical magnitudes but with opposite signs. The mean planes of the quinoline rings in the two independent mol-ecules are almost parallel, with a dihedral angle of only 0.16?(3)° between them, and the mutual orientation of these rings permits significant ?-? stacking inter-actions between them [centroid-centroid distances = 3.7579?(15) and 3.7923?(15)?Å]. In addition, the bimolecular aggregates which are related by translation along [010] are linked by a further ?-? stacking inter-action [centroid-centroid distance = 3.7898?(15)?Å], so forming a ?-stacked chain running parallel to [010]. However, there are no C-H?N hydrogen bonds in the structure nor, despite the number of independent aromatic rings, are there any C-H?? hydrogen bonds; hence there are no direction-specific inter-actions between adjacent ?-stacked chains.

Crystal structure of ethyl 2-chloro-6-methyl-quinoline-3-carboxyl-ate.

Project description:In the title compound, C13H12ClNO2, the dihedral angle between the planes of the quinoline ring system (r.m.s. deviation = 0.029 Å) and the ester group is 54.97 (6)°. The C-O-C-Cm (m = meth-yl) torsion angle is -140.62 (16)°. In the crystal, mol-ecules inter-act via aromatic π-π stacking [shortest centroid-centroid separation = 3.6774 (9) Å] generating (010) sheets.

Ethyl 3-(2-chloro-5,8-dimeth-oxy-quinolin-3-yl)-2-cyano-oxirane-2-carboxyl-ate.

Project description:The title mol-ecule, C(17)H(15)ClN(2)O(5), contains a quinolyl unit linked to a functionalized oxirane system with a 2,3-trans arrangement of the substituents (ester group versus quinol-yl). The structure can be described as being built up from zigzag layers parallel to (1[Formula: see text]0). The heterocyclic ring of the quinolyl unit forms a dihedral angle of 60.05?(1)° with the oxirane plane. The crystal packing is stabilized by inter-molecular C-H?O and C-H?N hydrogen bonding, resulting in the formation of an infinite three-dimensional network and reinforcing the cohesion between the layers.

Crystal structure of dimethyl 4,4'-di-meth-oxy-biphenyl-3,3'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the benzene rings are coplanar due to the centrosymmetric nature of the mol-ecule, with an inversion centre located at the midpoint of the C-C bond between the two rings. Consequently, the methyl carboxyl-ate substituents are oriented in a trans fashion with regards to the bond between the benzene rings. The methyl carboxyl-ate and meth-oxy substituents are rotated slightly out of plane relative to their parent benzene rings, with dihedral and torsion angles of 18.52 (8) and -5.22 (15)°, respectively. The shortest O⋯H contact between neighbouring mol-ecules is about 2.5 Å. Although some structure-directing contributions from C-H⋯O hydrogen-bonding inter-actions are possible, the crystal packing seems primarily directed by weak van der Waals forces.

Crystal structure, DFT study and Hirshfeld surface analysis of ethyl 6-chloro-2-eth-oxy-quinoline-4-carboxyl-ate.

Project description:In the title quinoline derivative, C14H14ClNO3, there is an intra-molecular C-H⋯O hydrogen bond forming an S(6) graph-set motif. The mol-ecule is essentially planar with the mean plane of the ethyl acetate group making a dihedral angle of 5.02 (3)° with the ethyl 6-chloro-2-eth-oxy-quinoline mean plane. In the crystal, offset π-π inter-actions with a centroid-to-centroid distance of 3.4731 (14) Å link inversion-related mol-ecules into columns along the c-axis direction. Hirshfeld surface analysis indicates that H⋯H contacts make the largest contribution (50.8%) to the Hirshfeld surface.

Crystal structure of ethyl 2-(3,5-di-fluoro-phen-yl)quinoline-4-carboxyl-ate.

Project description:In the title compound, C18H13F2NO2, the two rings of the quinoline system are fused almost coaxially, with a dihedral angle between their planes of 2.28?(8)°. The plane of the attached benzene ring is inclined to the plane of the quinoline system by 7.65?(7)°. The carboxyl-ate group attached to the quinoline system is in an anti-periplanar conformation. There is a short intra-molecular C-H?O contact involving the carbonyl group. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming chains lying in the (1-10) plane.
