catena-Polybis­(1H-benzimidazole-κN 3)palladium(II)-μ-benzene-14-dicarboxyl­ato-κ2 O 1:O 4

摘要

In the title compound, [Pd(C8H4O4)(C7H6N2)2]n, the Pd atom is tetra­coordinated by two carboxyl­ate O atoms from two benzene-1,4-dicarboxyl­ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra­hedral PdO2N2 geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N—H⋯O hydrogen bonds help to stabilize the crystal structure.
