Abstract
In the title complex, Ba(C(7)H(3)NO(4)), the coordination geometry around the Ba(II) ion can be described as a distorted bicapped trigonal-prismatic BaNO(7) arrangement. The pyridine-2,4-dicarb-oxy-lic acid ligands exhibit a new coordination mode. Adjacent metal centers are linked by the O atoms of the pyridine-2,4-dicarb-oxy-lic acid ligands, and then form a three-dimensional supra-molecular polymeric framework.
摘要
在标题配合物[Ba(C₇H₃NO₄)]ₙ中，Ba(II)离子周围的配位几何构型可描述为一种扭曲的双帽三角棱柱形BaNO₇排列。吡啶-2,4-二羧酸配体呈现出一种新的配位模式。相邻的金属中心通过吡啶-2,4-二羧酸配体的O原子相连，进而形成一个三维超分子聚合物框架。
