Abstract:
The thermal analysis of Fe(II), Ni(II) and Cu(II) complexes with 1, 3, 5-trimethyl hexahydro-triazine (TMAZ) and 1, 4, 7-triazacyclononane (TACN) were studied by microanalysis, TG and DTA techniques. Metal -TMAZ complexes shows some what similar TG and DTA profiles when heated in N2 atmosphere. An endothermic peak appears in the range 60-130oC which attributed to liberation of the organic ligand. TACN complexes show exothermic peak in the range 200-245oC proceeded to endothermic peak for dehydration of metal chelates in the range 125-155oC. The exothermic peak, corresponding to rapid mass-loss in TG curves, which may be due to oxidation reduction reaction. A relative thermal stability of metal complexes reported.
