Abstract

The thermal stabilities of bis salicylidene adipic dihydrazone derivatives and their complexes with divalent Mn, Co, Ni, Cu and Zn were studied and discussed in terms of structure and type of metal ions. TG curves display mostly four steps of thermal decomposition. The first step is due to dehydration, then the elimination of the acetate anions followed by the decomposition of the ligand in two interacting steps. The activation energies E a were evaluated and discussed in accordance with the structure of the complexes which have been previously characterized by elemental analysis and IR spectra. It was found that the activation energies of the complexes based on bis salicylidene adipic dihydrazone were higher than those of the dihydroxy derivative.
