POLYMER COMPLEXES .30. NOVEL POLYMER COMPLEXES PREPARED IN THE PRESENT INVESTIGATION FROM POLY[1-ACRYLAMIDO-2(2-PYRIDYL)ETHANE]

Novel polymeric metal complexes of copper(II), nickel(II), cobalt(II), and zinc(II) with poly[1-acrylamido-2(2-pyridyl)ethane] (PAEPH) have been prepared and characterized by chemical and thermal analyses, mola r conductivity, magnetic susceptibility measurements, and infrared, el ectronic, and EPR spectra. The visible and EPR spectral studies indica ted that the Cu(II) complexes have either a square planar or a distort ed octahedral geometry. From the EPR spectra of the Cu(II) polymer com plexes, various parameters were calculated. The crystal field paramete rs (Dq, B, and beta) for the Co(II) and Ni(II) polymer complexes were calculated and agree fairly well with the values reported for known oc tahedral complexes. The infrared spectral studies showed a neutral and /or monobasic bidentate behaviour of PAEPH with the nitrogen donor sys tem.
