title: catena-Poly[[bis-[μ-2-(3-pyrid-yl)-1H-benzimidazole]-κN:N;κN:N-disilver(I)]-μ-2,5-dicarboxy-benzene-1,4-dicarboxyl-ato-κO:O].
abstract: The title coordination polymer, [Ag(2)(C(10)H(4)O(8))(C(12)H(9)N(3))(2)](n), was prepared by a hydro-thermal method. The Ag(I) atom exists in a strongly distorted trigonal coordination environment. Two Ag(I) ions related by an inversion centre are coordinated by two 2-(3-pyrid-yl)benzimidazole ligands, forming a centrosymmetric cyclic dimer. The bridging bidentate 2,5-dicarboxy-benzene-1,4-dicarboxyl-ate 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 intra-molecular O-H⋯O hydrogen bond. Finally, inter-molecular N-H⋯O hydrogen bonds aggregate the chains into a three-dimensional framework.
