Abstract

In the title compound, Cd(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2), the Cd(II) ion has inversion symmetry and is coordinated by O atoms from two water mol-ecules and two bridging 2,2'-(μ-p-phenyl-enedi-oxy)diacetate ligands and two N atoms from two 4,4'-bipyridine ligands, giving a slightly distorted octa-hedral geometry. The diacetate and 4,4'-bipyridine ligands also lie across inversion centers. The bridging ligands form layers parallel to (11[Formula: see text]), with adjacent layers inter-connected via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate O atoms, giving a three-dimensional supra-molecular architecture.

摘要

在标题化合物[Cd(C₁₀H₈O₆)(C₁₀H₈N₂)(H₂O)₂]ₙ中，Cd(II)离子具有反演对称性，由两个水分子的O原子、两个桥连的2,2'-(μ-对苯二氧基)二乙酸酯配体以及两个4,4'-联吡啶配体的两个N原子配位，形成略微扭曲的八面体几何构型。二乙酸酯和4,4'-联吡啶配体也位于反演中心上。桥连配体形成平行于(11[化学式：见原文])的层，相邻层通过配位水分子与羧酸根O原子之间的O—H⋯O氢键相互连接，形成三维超分子结构。
