Abstract

In the title coordination polymer, Nd(2)(C(10)H(8)O(4))(3)(H(2)O)(2), each of the two Nd(III) ions is nine-coordinated by eight O atoms from six different 2,2'-(m-phenyl-ene)diacetate (pda) bivalent anions and by one O atom from a water mol-ecule, forming a distorted tricapped trigonal-prismatic coordination geometry. Eight Nd(III) ions and 12 pda ligands form a large [Nd(8)(pda)(12)] ring, and four Nd(III) ions and six pda ligands form a small [Nd(4)(pda)(6)] ring. These rings are further connected by the coordination inter-actions of pda ligands and Nd(III), generating a three-dimensional supra-molecular framework.

摘要

在标题配位聚合物[Nd₂(C₁₀H₈O₄)₃(H₂O)₂]ₙ中，两个Nd(III)离子中的每一个都由来自六个不同的2,2'-间苯二甲酸二乙酸酯（pda）二价阴离子的八个O原子和来自一个水分子的一个O原子九配位，形成扭曲的三帽三棱柱配位几何构型。八个Nd(III)离子和12个pda配体形成一个大的[Nd₈(pda)₁₂]环，四个Nd(III)离子和六个pda配体形成一个小的[Nd₄(pda)₆]环。这些环通过pda配体和Nd(III)的配位相互作用进一步连接，生成三维超分子框架。
