Abstract :N,N-dimethyl-N`-benzoylthiourea insert ignore into journalissuearticles values(DMBT); complexes of Niinsert ignore into journalissuearticles values(II);, Cuinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II); and Pdinsert ignore into journalissuearticles values(II); were synthesised. The thermal decomposition of these metal complexes was investigated by TG, DTG and DTA. A GC-MS combined system was used to identify the products during pyrolytic decomposition. The pyrolytic end-products were identified by X-ray powder diffraction. The thermoanalytical data of these complexes are presented in this communication. The kinetic analysis of the thermogravimetric data was performed by using the Coats-Redfern and Horowitz-Metzger methods. All the metal complexes except Cuinsert ignore into journalissuearticles values(II); complex undergo decomposition in three stages and NiS, CoS, Pd, and Cu remained as end-products of the complexes.
