Abstract

The structure of the title compound, Li(C(5)H(3)N(2)O(2))(H(2)O), contains an Li(I) ion with a distorted trigonal-bipyramidal coordination environment involving the N and O atoms of pyrazine-2-carboxyl-ate ligands with a bridging carboxyl-ate group, and two aqua O atoms also in a bridging mode. The symmetry-related Li(I) ions bridged by a carboxyl-ate O atom and a coordinating water O atom form an Li(2)O(2) unit with an Li⋯Li distance of 3.052 (4) Å, which generates mol-ecular ribbons propagating in the c-axis direction. The ribbons are held together by a network of O-H⋯O hydrogen bonds in which the coordinating water mol-ecules act as donors and the carboxyl-ate O atoms as acceptors.

摘要

标题化合物[Li(C₅H₃N₂O₂)(H₂O)]ₙ的结构中，Li(I)离子具有扭曲的三角双锥配位环境，涉及吡嗪 - 2 - 羧酸盐配体的N和O原子以及一个桥连羧酸盐基团，还有两个以桥连模式存在的水分子O原子。由一个羧酸盐O原子和一个配位水分子O原子桥连的对称相关Li(I)离子形成一个Li₂O₂单元，Li⋯Li距离为3.052 (4) Å，生成沿c轴方向传播的分子带。这些分子带通过O - H⋯O氢键网络维系在一起，其中配位水分子作为供体，羧酸盐O原子作为受体。
