title: catena-Poly[[(5-carb-oxy-2H-1,2,3-triazole-4-carboxyl-ato-κN,O)sodium]-di-μ-aqua-κO:O].
abstract: In the title coordination polymer, [Na(C(4)H(2)N(3)O(4))(H(2)O)(2)](n), 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.
