Abstract: In the crystal structure of the title compound, [Co(C₁₀H₄Cl₂NO₂)₂]_n, the Co^II cation lies on a twofold rotation axis. Each cation is N,O-chelated by the carboxylate anions of two 3,7-dichloroquinoline-8-carboxylate ligands. The second carboxylate O atom of each ligand coordinates to the Co^II cation of an adjacent molecule, linking the cations into a linear chain. Strong interchain - stacking interactions are observed in the crystal structure (perpendicular distance 3.42 Å, centroid-to-centroid distance 3.874 Å)
