The polymeric title compound, {[Dy₂(C₈H₄O₅)₃(C₁₀H₈N₂)₂(H₂O)₂]·2H₂O}_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-hydroxyisophthalate (hip) ligands and one 2,2'-bipyridine (bpy) ligand and the other by three hip ligands, one bpy ligand and two water molecules. The Dy^III ions are bridged by the carboxylate groups of the hip ligands, forming a three-dimensional framework. O-HO hydrogen bonds are present in the crystal structure.
