Synthesis, crystal structure and properties of a one-dimensional polymeric copper(II) complex of tetrachlorophthalate

Abstract

The coordination polymer [Cu2L2(H2O)(6) . 2(H2O)](n) (L = mu-tetrachlorophthalate dianion) has been synthesized and characterized by X-ray crystallography, i.r. spectroscopy, electronic spectroscopy and cyclic voltammetry. The structure of the complex is a one-dimensional zigzag chain. The i.r. spectra reveal that the tetrachlorophthalate groups are bismonodentate ligands, and this is confirmed by the crystal structure determination. Cyclic voltammetry reveals two steps of a quasi-reversible oxidation-reduction processes for the complex.
