In the crystal structure of the title compound, Co(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O), 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-nitro-isophthalate (ndc) dianion, one N,N'-bidentate 2,2'-bipyridyl ligand and one water mol-ecule. A symmetry-generated O,O'-bidentate ndc dianion completes the cobalt coordination environment, which could be described as very distorted cis-CoN(2)O(4) octa-hedral. The bridging ndc ligands result in parallel chains running along the a direction, and O-H⋯O hydrogen bonds arising from the water mol-ecules complete the structure.
在标题化合物[Co(C₈H₃NO₆)(C₁₀H₈N₂)(H₂O)]ₙ的晶体结构中，存在两个对称独立的一维配位聚合物，它们通过非晶体学反演对称性大致相关。每条锯齿链由一个Co(II)离子、一个O-单齿5-硝基间苯二甲酸（ndc）二价阴离子、一个N,N'-双齿2,2'-联吡啶配体和一个水分子构成。一个通过对称性产生的O,O'-双齿ndc二价阴离子完善了钴的配位环境，其可被描述为严重扭曲的顺式-CoN₂O₄八面体。桥连的ndc配体导致平行链沿a方向延伸，由水分子形成的O-H⋯O氢键完善了该结构。
