Synthesis,structure and electrochemical properties of a zinc(II) coordination polymer based on ferrocenyl-substituted carboxylate and bis (benzimidazolyl)pentane ligands

By reaction of two ligands, Na(o-OOCC₆H₄COFc) (Fc?=?(η⁵–C₅H₅)Fe(η⁵–C₅H₄)) and 1,1′–(1,5–pentamethylene)bis-1H-benzimidazole (pbbm), with Zn(OAc)₂?·?2H₂O in methanol solution, we have synthesized a zinc(II) coordination polymer Zn(o-OOCC₆H₄COFc)₂(pbbm)] _n . The polymer was characterized by X-ray single crystal diffraction, IR spectroscopy, and elemental analysis. Each Zn atom was connected by two pbbm ligands, leading to an infinite one-dimensional chain. Two monodentate o-FcCOC₆H₄COO^? anions completed the coordination sphere of the central Zn(II) ion. The polymer's electrochemical properties were investigated in DMF solution.
