چکیده
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.

In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help ...
