Abstract

In the title complex, La(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)(2), the La(III) ion is coordinated by eight O atoms from two 2-oxido-pyridinium-3-carboxyl-ate ligands, two oxalate ligands and two water mol-ecules in a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups link adjacent La(III) ions, forming two-dimensional layers that are further linked by N-H⋯O and O-H⋯O hydrogen bonds.

摘要

在标题配合物[La(C₆H₄NO₃)(C₂O₄)(H₂O)₂]ₙ中，La(III)离子由来自两个2-氧化吡啶-3-羧酸根配体、两个草酸根配体和两个水分子的八个O原子配位，形成扭曲的双帽四方反棱柱几何构型。羧酸根基团连接相邻的La(III)离子，形成二维层，这些二维层通过N-H⋯O和O-H⋯O氢键进一步连接。
