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)](n), 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.
