Abstract

The paper describes the synthesis and properties of copper (II), nickel (II), cobalt (II) complexes with macromolecular ligands. Chitosan-polydimethylsiloxane graft and crosslinked copolymers were used as coordinating species. The chemical structure of metal complexes was investigated by FT-IR spectroscopy. As proved by X-ray diffraction, the metal complexes are materials of low crystallinity and their supermolecular structure depends on cation nature. The linking of metal cations to CS-PDMS copolymers slightly increases the materials conductivity..
