Özet
The N-pyrrolidine-N′-(2-chlorobenzoyl)thiourea, HL, and their Ni(II), Cu(II), and Co(III) complexes (NiL 2, CuL 2, and CoL 3) have been synthesized and characterized. The thermal decomposition reactions of all the compounds have been investigated by DTA/TG combined systems. The mass spectroscopy technique has been used to identify the products during pyrolytic decomposition. The pyrolytic final products have been analyzed by X-ray powder diffraction method. After comparison of thermogravimetric and mass results of HL, NiL 2, CuL 2, and CoL 3, the decomposition mechanism of these compounds have been suggested. The thermal stability of theNi(II) and Cu(II) complexes according to the thermogravimetric curves follows the sequence: NiL 2
