Diethyl 7,7'-di-chloro-4-oxo-4H-[1,4'-bi-quinoline]-3,3'-di-carboxyl-ate.

ABSTRACT: In the title compound, C24H18Cl2N2O5, the quinoline and quinolinone moieties are nearly perpendicular to each other, forming a dihedral angle of 82.36?(3)°. In the crystal, mol-ecules form a halogen bond between a Cl atom of a quinolinone moiety and the N atom of the quinoline moiety of the inversion equivalent [Cl?N = 3.106?(3)?Å]. The mol-ecules also form two kinds of C-H?O hydrogen-bonded centrosymmetric inversion dimers, making chains along the c-axis direction which are further inter-linked by the halogen bonds into layers parallel to the bc plane.

In the title compound, C24H18Cl2N2O5, the quinoline and quinolinone moieties are nearly perpendicular to each other, forming a dihedral angle of 82.36 (3)°. In the crystal, mol-ecules form a halogen bond between a Cl atom of a quinolinone moiety and the N atom of the quinoline moiety of the inversion equivalent [Cl⋯N = 3.106 (3) Å]. The mol-ecules also form two kinds of C-H⋯O hydrogen-bonded centrosymmetric inversion dimers, making chains along the c-axis direction which are further inter-linked ...[more]

Project description:In the title mol-ecule, C24H20N2O5, the quinoline and quinolinone moieties are practically perpendicular to each other, forming a dihedral angle of 89.06?(3)°.

Diethyl 4-(biphenyl-4-yl)-2,6-dimethyl-1,4-di-hydro-pyridine-3,5-di-carboxyl-ate.

Project description:The title compound, C25H27NO4, has a flattened di-hydro-pyridine ring. The benzene and phenyl rings are synclinal to one another, forming a dihedral angle of 49.82?(8)°; the axis of the biphenyl rings makes an 81.05?(9)° angle to the plane of the di-hydro-pyridine ring. In the crystal, N-H?O hydrogen bonds link the mol-ecules into chain motifs running along the a-axis direction. The chains are cross-linked by C-H?O inter-actions, forming sheet motifs running slightly off the (110) plane, together with an intermolecular interaction between head-to tail biphenyl groups, thus making the whole crystal packing a three-dimensional network. Intra-molecular C-H?O hydrogen bonds are also observed.

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.

Diethyl 4-(2-meth-oxy-phen-yl)-2,6-di-methyl-1,4-di-hydro-pyridine-3,5-di-carboxyl-ate.

Project description:In the title compound, C20H25NO5, the di-hydro-pyridine ring adopts a flattened boat conformation. The meth-oxy-phenyl ring is almost perpendicular to the mean plane of the pyridine ring [dihedral angle = 88.42?(3)°]. The two carbonyl units adopt a synperiplanar conformation with respect to the double bonds in the di-hydro-pyridine ring. In the crystal, mol-ecules are connected by N-H?O hydrogen bonds into R 4 (4)(24) tetra-meric rings. A region of disordered electron density, located at the center of four adjacent mol-ecules, was treated with the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. It is probably the result of traces of the solvent of crystallization and was not taken into account during the structure refinement.

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.

Diaqua-bis-(2,2'-bi-1H-imidazole)-man-ganese(II) benzene-1,4-di-carboxyl-ate.

Project description:The asymmetric unit of the title compound, [Mn(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(4)O(4)), contains one-half each of the centrosymmetric cation and anion. The Mn(II) atom is coordinated by four N atoms [Mn-N = 2.2168?(14) and 2.2407?(14)?Å] from two 2,2'-biimidazole ligands and two water mol-ecules [Mn-O = 2.2521?(14)?Å] in a distorted octa-hedral geometry. Inter-molecular N-H?O and O-H?O hydrogen bonds consol-idate the crystal packing, which also exhibits ?-? inter-actions between five-membered rings, with a centroid-centroid distance of 3.409?(2)?Å.

Dimethyl 3,3'-di-meth-oxy-biphenyl-4,4'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh-oxy groups form C-C-C-O torsion angles of -18.3 (3) and -27.7 (3)° with the attached rings, as a result of steric hindrances from the nearby meth-oxy groups. In the absence of stacking inter-actions and with no H⋯O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter-actions.

3,4-Di-methyl-phenyl quinoline-2-carboxyl-ate.

Project description:In the title compound, C18H15NO2, the dihedral angle between the mean planes of the quinoline ring system and the phenyl ring is 48.1 (5)°. The mean plane of the carboxyl-ate group is twisted from the mean planes of the latter by 19.8 (8) and 64.9 (5)°, respectively. The crystal packing features weak C-H⋯O inter-actions, which form chains along [010].

Diethyl 3,3'-(phenyl-methyl-ene)bis-(1H-indole-2-carboxyl-ate).

Project description:In the title compound, C(29)H(26)N(2)O(4), the benzene ring is twisted by 73.5 (5) and 84.9 (3)° with respect to the mean planes of the two indole ring systems; the mean planes of the indole ring systems are oriented at a dihedral angle of 82.0 (5)°. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into chains.

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.
