Magnetic Properties of Some New Polymeric Chelating Complexes.I.

摘要

A new series of metallopolymer complexes derived from the homopolymer poly(2-acrylamide) benzoic acid (PBA) through some transition metals,Cu(II),Ni(II),and Co(II),were prepared.The compounds were synthesized and characterized through different techniques.Their molecular structures were assumed based on the different spectral data [ultraviolet (UV) and infrared (IR)].The magnetic behavior of these metallopolymer complexes was measured as a function of magnetic field strength [1.65-0.85 tesla (T)] at room temperature (RT) (300K) and as a function of temperature (4.2-300 K) at a magnetic field strength of 1.7 T.Based on the magnetic data,the mechanisms of magnetic interaction are explained related to the stereochemistry of these metallopolymer complexes.
