Abstract

In the title coordination polymer, [Na(C4H2N3O4)(H2O)2]n, the NaI atom is six-coordinated by one O atom and one N atom from a 2H-1,2,3-triazole-4-carboxy-5-carboxylate ligand and four O atoms from four water molecules, forming a distorted octahedal geometry. The NaI atoms are bridged by water molecules into a chain structure along [100]. Intermolecular N—H...O, O—H...N and O—H...O hydrogen bonds connect the chains. An intramolecular O—H...O hydrogen bond between the carboxylate groups is observed.
