2,3-Diamino-pyridinium 4-meth-oxy-quinoline-2-carboxyl-ate.

ABSTRACT: In the 4-meth-oxy-quinoline-2-carboxyl-ate anion of the title salt, C5H8N3(+)·C11H8NO3(-), the dihedral angle between the quinoline ring system and the carboxyl-ate group is 16.54?(15)°. In the crystal, the cations and anions are linked via N-H?O and N-H?N hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R2(2)(9) and R4(2)(8) ring motifs. These units are further connected via N-H?O hydrogen bonds into a layer parallel to the bc plane. The crystal structure is also stabilized by weak C-H?O hydrogen bonds and ?-? inter-actions between pyridine rings [centroid-centroid distance = 3.5886?(8)?Å] and between pyridine and benzene rings [centroid-centroid distance = 3.6328?(8)?Å].

In the 4-meth-oxy-quinoline-2-carboxyl-ate anion of the title salt, C5H8N3(+)·C11H8NO3(-), the dihedral angle between the quinoline ring system and the carboxyl-ate group is 16.54 (15)°. In the crystal, the cations and anions are linked via N-H⋯O and N-H⋯N hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R2(2)(9) and R4(2)(8) ring motifs. These units are further connected via N-H⋯O hydrogen bonds into a layer parallel to the bc plane. The crystal structure is also stabilized by wea ...[more]

Project description:The asymmetric unit of the title proton-transfer compound, C(5)H(8)N(3) (+)·C(7)H(4)NO(4) (-), consists of one mono-deprotonated pyridine-2,6-dicarb-oxy-lic acid as anion and one protonated 2,3-diamino-pyridine as cation.

2,3-Diamino-pyridinium 4-carb-oxy-butano-ate.

Project description:In the title mol-ecular salt, C(5)H(8)N(3) (+)·C(5)H(7)O(4) (-), the 2,3-diamino-pyridine mol-ecule is protonated at the pyridine N atom. The cation is essentially planar, with a maximum deviation of 0.015 (2) Å, and the anion adopts an extended conformation. In the crystal, the hydrogen glutarate (4-carb-oxy-butano-ate) anions are self-assembled through O-H⋯O hydrogen bonds, forming chains. The cations are connected to the anion chains via N-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal structure also features aromatic π-π inter-actions between the pyridinium cations, with a centroid-centroid distance of 3.4464 (10) Å.

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-chloro-5,8-di-meth-oxy-quinoline-3-carboxyl-ate.

Project description: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.

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.

4-Meth-oxy-quinolinium-2-carboxyl-ate dihydrate.

Project description:The title hydrated quinoline derivative, C(11)H(9)NO(3)·2H(2)O, crystallizes as a zwitterion in which the quinoline N atom is protonated. The quinoline ring is essentially planar, with a maximum deviation of 0.017 (2) Å. An intra-molecular N-H⋯O hydrogen bond between the protonated N atom and the O atom of the carboxyl-ate group in the zwitterion forms an S(5) ring motif. In the crystal, the zwitterions are connected into inversion dimers via pairs of N-H⋯O and C-H⋯O hydrogen bonds with R(2) (2)(4) and R(1) (2)(6) motifs. The water mol-ecules are connected via O-H⋯O hydrogen bonds, forming supra-molecular chains along the c axis. Furthermore, the chains and the dimers are connected via O-H⋯O hydrogen bonds, forming ladder-like supra-molecular ribbons along the c axis.
