Poly[aqua(μ₃-pyridazine-4-carboxylato-κ²O:O:O′)lithium]

Abstract

The structure of the title compound, [Li(C5H3N2O2)(H2O)]n, is composed of centrosymmetric dimers in which two LiI ions are bridged by a carboxyl­ate O atom, each donated by a ligand, acting in a bidentate mode. The second carboxyl­ato O atoms bridge the dimers to LiI ions in adjacent dimers, forming mol­ecular layers parallel to (001). Each LiI ion is coordinated by two bridging carboxyl­ate O atoms, a bridging carboxyl­ate O atom donated by the adjacent dimer and an aqua O atom, resulting in a distorted tetra­hedral coordination geometry. The layers are held together by O—H⋯N hydrogen bonds in which coordinated water O atoms act as donors and ligand hetero-ring N atoms as acceptors.
