چکیده
The asymmetric unit of the title compound, C(9)H(5)Cl(2)N, consists of two crystallographically independent mol-ecules. In both mol-ecules the quinoline ring system is essentially planar [maximum deviations from the best plane of 0.0232 (13) 0.0089 (15) Å]. The angle between these planes is 22.40 (3)°. Conformers A and B are arranged face-to-face along the c axis, forming alternating pairs in the order AABB. The inter-planar distances AA, AB and BB are 3.3166 (11), 3.2771 (11) and 3.3935 (11) Å, respectively. The crystal packing is stabilized by weak C-H⋯Cl and C-H⋯N inter-actions.

In the crystal structure of the title compound, [Co(C(10)H(4)Cl(2)NO(2))(2)](n), the Co(II) cation lies on a twofold rotation axis. Each cation is N,O-chelated by the carboxyl-ate anions of two 3,7-dichloro-quinoline-8-carboxyl-ate ligands. The second carboxyl-ate O atom of each ligand coordinates to the Co(II) cation of an adjacent mol-ecule, linking the cations into a linear chain. Strong int...

In the title compound, [Zn(C(10)H(4)Cl(2)NO(2))(2)(H(2)O)(2)]·H(2)O, the Zn atom has a distorted square-pyramidal geometry comprising two O atoms and one N atom from two distinct 3,7-dichloro-quinoline-8-carboxyl-ate ligands, and two water mol-ecules. The free water mol-ecules are involved in inter-molecular O-H⋯O hydrogen bonding with the coordinated water mol-ecules and carboxyl-ate O atoms, ...

The title compound, C(12)H(9)Cl(2)NO(2), was prepared by the esterification of 3,7-dichloro-quinoline-8-carboxylic acid with triethyl phosphite. The crystal structure is stabilized by aromatic π-π stacking between the benzene and the pyridine rings of neighbouring mol-ecules [centroid-centroid distances = 3.716 (2) and 3.642 (2) Å]. In addition, weak inter-molecular C-H⋯N hydrogen bonds are pre...
