In the title coordination polymer, Na(C(4)H(2)N(3)O(4))(H(2)O)(2), the Na(I) atom is six-coordinated by one O atom and one N atom from a 2H-1,2,3-triazole-4-carb-oxy-5-carboxyl-ate ligand and four O atoms from four water mol-ecules, forming a distorted octa-hedal geometry. The Na(I) atoms are bridged by water mol-ecules into a chain structure along [100]. Inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds connect the chains. An intra-molecular O-H⋯O hydrogen bond between the carboxyl-ate groups is observed.
在标题配位聚合物[Na(C₄H₂N₃O₄)(H₂O)₂]ₙ中，Na(I)原子由来自2H - 1,2,3 - 三唑 - 4 - 羧基 - 5 - 羧酸盐配体的一个O原子和一个N原子以及来自四个水分子的四个O原子进行六配位，形成扭曲的八面体几何构型。Na(I)原子通过水分子沿[100]桥连形成链状结构。分子间的N - H⋯O、O - H⋯N和O - H⋯O氢键连接这些链。观察到羧酸盐基团之间存在分子内O - H⋯O氢键。
