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)), degrees C, respectively. Based on half degradation temperature parameters Cu(II) and Zn(II) complexes were more resistant than the others.eninfo:eu-repo/semantics/closedAccessoligomer metal complexesoligo-p-nitrophenilazomethinephenolCu(II) complexNi(II) complexZn(II) complexCo(II) complexArticle202219226WOS:000242505500005Q4
