MAGNETIC-PROPERTIES OF SOME NEW POLYMERIC CHELATING COMPLEXES - I

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 synthesi zed and characterized through different techniques. Their molecular st ructures were assumed based on the different spectral data [ultraviole t (UV) and infrared (IR)]. The magnetic behavior of these metallopolym er complexes was measured as a function of magnetic field strength [1. 65-0.85 tesla (T)] at room temperature (RT) (300 K) and as a function of temperature (4.2-300 K) at a magnetic field strength of 1.7 T. Base d on the magnetic data, the mechanisms of magnetic interaction are exp lained and related to the stereochemistry of these metallopolymer comp lexes. (C) 1999 John Wiley & Sons, Inc.
