The properties of oligomer-metal complexes were studied by elemental, FT-IR and magnetic moments analyses. The thermal stabilities of the oligomer-metal complexes were compared by thermogravimetric (TG) and differential thermal (DTA) analyses. According to TG, oligomer-metal complexes were stable against to temperature and thermooxidative decomposition. The weight losses of oligomer-metal complexes were found to be 5 and 50% at 200 and > 850 (Cu(II)), 172 and 600 (Ni(II)), 252 and > 850 (Zn(II)) and 174 and 510 (Co(II)), °C, respectively. Based on half degradation temperature parameters Cu(II) and Zn(II) complexes were more resistant than the others. © 2006 Chemical Society of Ethiopia.eninfo:eu-repo/semantics/closedAccessCo(II) complexCu(II) complexNi(II) complexOligo-p-nitrophenilazomethinephenolOligomer metal complexesZn(II) complexArticle202219226Q3
