title: Poly[[diaquabis(2,2'-bipyridine-κN,N')(μ(3)-5-hydroxyisophthalato-κO,O:O,O:O)(μ(3)-5-hydroxy-isophthalato-κO,O:O:O)(μ(2)-5-hydroxyisophthalato-κO,O:O)didysprosium(III)] dihydrate].
abstract: The polymeric title compound, {[Dy(2)(C(8)H(4)O(5))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)]·2H(2)O}(n), contains two independent Dy(III) ions, both of which are nine-coordinated in a distorted tricapped trigonal-prismatic geometry. One Dy(III) ion is coordinated by five 5-hy-droxy-isophthalate (hip) ligands and one 2,2'-bipyridine (bpy) ligand and the other by three hip ligands, one bpy ligand and two water mol-ecules. The Dy(III) ions are bridged by the carboxyl-ate groups of the hip ligands, forming a three-dimensional framework. O-H⋯O hydrogen bonds are present in the crystal structure.
