Di-μ-aqua-bis­[aqua­(5-carboxyl­ato-1H-1,2,3-triazole-4-carb­oxy­lic acid-κ(2) N (3),O (4))lithium]

The crystal structure of the title compound, [Li(2)(C(4)H(2)N(3)O(4))(2)(H(2)O)(4)], contains centrosymmetric dinuclear mol­ecules in which two Li(I) ions are bridged by two water O atoms. The metal ion is coordinated by one N,O-bidentate ligand and three water O atoms (one of them is symmetry generated), with one of the bridging water O atoms in the apical position of a distorted square pyramid. The carboxyl­ate group that participates in coordination to the metal ion remains protonated; the other is deprotonated and coordination inactive. An intra­molecular O—H⋯O hydrogen bond between carboxyl­ate groups is observed. In the crystal, dimers are linked by O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds, generating a three-dimensional network.
