چکیده
The title compound, [Dy(2)(C(3)H(2)O(4))(3)(H(2)O)(6)](n), 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.

The title dysprosium coordination polymer, {[Dy(2)(C(10)H(8)O(6))(3)(H(2)O)(2)]·2H(2)O}(n), was synthesized by reacting dysprosium(III) nitrate and the flexible ligand (p-phenyl-enedi-oxy)diacetic acid under hydro-thermal conditions. Each Dy(III) ion is coordinated by nine O atoms in a tricapped trigonal prismatic geometry. The DyO(9) polyhedra form layers parallel to the bc plane. The rigid be...
