Abstract: In the crystal structure of the title compound, [Co(C₈H₃NO₆)(C₁₀H₈N₂)(H₂O)]_n, there are two symmetry-independent one-dimensional coordination polymers, which are approximately related by noncrystallographic inversion symmetry. Each zigzag chain is constructed from one Co^II ion, one O-monodentate 5-nitroisophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water molecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN₂O₄ octahedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-HO hydrogen bonds arising from the water molecules complete the structure.
