2N2:N3;2N3:N2-disilver(I)]--2,5-dicarboxybenzene-1,4-dicarboxylato-2O2:O5]Abstract: The title coordination polymer, [Ag2(C10H4O8)(C12H9N3)2]n, was prepared by a hydrothermal method. The AgI atom exists in a strongly distorted trigonal coordination environment. Two AgI ions related by an inversion centre are coordinated by two 2-(3-pyridyl)benzimidazole ligands, forming a centrosymmetric cyclic dimer. The bridging bidentate 2,5-dicarboxybenzene-1,4-dicarboxylate ligand is also located on an inversion centre and connects the binuclear units, generating a one-dimensional polymer. The almost-planar conformation of this ligand allows it to form a strong intramolecular O-H
O hydrogen bond. Finally, intermolecular N-HO hydrogen bonds aggregate the chains into a three-dimensional framework.
