The title compound, Dy(2)(C(3)H(2)O(4))(3)(H(2)O)(6), forms a coordination polymeric structure comprising hydrated dysprosium ions and malonate ligands. In the asymmetric unit, there are one dysprosium ion, one and a half malonate ligands, and three water mol-ecules. Each Dy(III) atom is coordinated by six O atoms from four malonate ligands and by three water mol-ecules, and displays a tricapped trigonal-prismatic coordination geometry. The malonate ligands adopt two types of coordination mode, linking dysprosium centres to form a three-dimensional coordination polymer. The extensive network of hydrogen bonds in this polymer enhances the structural stability.
标题化合物[Dy₂(C₃H₂O₄)₃(H₂O)₆]ₙ形成了一种包含水合镝离子和丙二酸酯配体的配位聚合物结构。在不对称单元中，有一个镝离子、一个半丙二酸酯配体和三个水分子。每个Dy(III)原子由来自四个丙二酸酯配体的六个O原子和三个水分子配位，呈现出一种三帽三棱柱配位几何构型。丙二酸酯配体采用两种配位模式，连接镝中心形成三维配位聚合物。该聚合物中广泛的氢键网络增强了结构稳定性。
