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.
聚合标题化合物{[Dy₂(C₈H₄O₅)₃(C₁₀H₈N₂)₂(H₂O)₂]·2H₂O}ₙ包含两个独立的Dy(III)离子,二者均以扭曲的三帽三角棱柱几何构型呈九配位。一个Dy(III)离子由五个5-羟基间苯二甲酸(hip)配体和一个2,2'-联吡啶(bpy)配体配位,另一个由三个hip配体、一个bpy配体和两个水分子配位。Dy(III)离子由hip配体的羧酸根基团桥连,形成三维骨架。晶体结构中存在O-H⋯O氢键。
