In the title coordination polymer, [AgTb(C7H3NO4)(C7H4NO4)(C2O4)0.5(H2O)2]n, the TbIII ion is eight-coordinated by three O atoms from three different pydc (H2pydc = pyridine-3,5-dicarboxylic acid) ligands, one O atom from one Hpydc ligand, two O atoms from one oxalate ligand and two water molecules in a distorted square-antiprismatic geometry. The AgI ion is coordinated in an almost linear fashion by two pyridyl N atoms from one pydc and one Hpydc ligand and has weak interactions with two carboxylate O atoms. The carboxylate groups of pydc and Hpydc ligands link Tb centers, forming a one-dimensional chain. The oxalate adopts a tetradentate bis-chelating coordination mode, connecting the chains into a two-dimensional layer. These layers are further assembled via [Ag(pydc)(Hpydc)] pillars and O-H...O and C-H...O hydrogen bonds into a three-dimensional coordination framework.
