The asymmetric unit of the title one-dimensional coordination polymer, catena-poly[[mu-pyridine-2,3-dicarboxylato-1kappaO:2kappa(2)N,O'-bis[diaquacobalt(II)]]-mu-pyridine-2,3-dicarboxylato-1kappa(2)N,O:2kappaO':1'kappaO'], Co(C(7)H(3)NO(4))(H(2)O)(2), is composed of a cobalt(II) ion, a pyridine-2,3-dicarboxylate dianion and two water molecules. The polymer has a zigzag structure consisting of a chain of edge-fused rings, and the polymer chains are linked by O-H.O hydrogen bonds into a three-dimensional framework.
标题一维配位聚合物，链状聚[[μ-吡啶-2,3-二羧酸根-1κO:2κ(2)N,O'-双[二水合钴(II)]]-μ-吡啶-2,3-二羧酸根-1κ(2)N,O:2κO':1'κO']，[Co(C₇H₃NO₄)(H₂O)₂]ₙ的不对称单元由一个钴(II)离子、一个吡啶-2,3-二羧酸二价阴离子和两个水分子组成。该聚合物具有由边缘稠合环链构成的之字形结构，并且聚合物链通过O-H…O氢键连接成三维骨架。
