Catena-Poly[cobalt(II)-bis-(?-3,7-dichloro-quinoline-8-carboxyl-ato-?N,O:O')].

ABSTRACT: 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 inter-chain ?-? stacking inter-actions are observed in the crystal structure (perpendicular distance 3.42?Å, centroid-to-centroid distance 3.874?Å).
