Abstract

The structure of the title compound, Li(C(5)H(3)N(2)O(2))(H(2)O), is composed of centrosymmetric dimers in which two Li(I) ions are bridged by a carboxyl-ate O atom, each donated by a ligand, acting in a bidentate mode. The second carboxyl-ato O atoms bridge the dimers to Li(I) ions in adjacent dimers, forming mol-ecular layers parallel to (001). Each Li(I) ion is coordinated by two bridging carboxyl-ate O atoms, a bridging carboxyl-ate O atom donated by the adjacent dimer and an aqua O atom, resulting in a distorted tetra-hedral 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.

摘要

标题化合物[Li(C₅H₃N₂O₂)(H₂O)]ₙ的结构由中心对称的二聚体组成，其中两个Li(I)离子由一个羧酸根O原子桥连，每个羧酸根O原子由一个配体提供，以双齿模式配位。第二个羧酸根O原子将二聚体与相邻二聚体中的Li(I)离子桥连，形成平行于(001)的分子层。每个Li(I)离子由两个桥连的羧酸根O原子、一个由相邻二聚体提供的桥连羧酸根O原子和一个水合O原子配位，形成扭曲的四面体配位几何构型。这些层通过O-H⋯N氢键结合在一起，其中配位水O原子作为供体，配体杂环N原子作为受体。
