Abstract

Metal Complexes of Pr (III), Gd(III) and Sm (III) with substituted naphthoic acid and
hydrazine ligand were prepared. Thermal behavior (TGA/DTA) of the complexes was studied and
kinetic parameter was determined by Coats-Redfern method. The TG and DTA data indicated that all
complexes are thermo stable up to 91.9 K. The data from thermo gravimetric analysis clearly
indicates that decomposition of the complexes proceeds in two or three steps .The decomposition of all
the complexes ended with the metal oxide. The tentative mechanism for the thermal decomposition has
been proposed.
