Spectroscopic and Thermal Studies of Some Palladium(II) Complexes with 2-amino-4-(4-subsistuted phenyl)thiazole Derivatives
Six new complexes of palladium(II) with a general formula [Pd(L)2Cl2], where L = 2-amino-4-(4-subsistuted phenyl)thiazole. The palladium complexes were prepared by the reaction of 2-amino-4-(4-subsistuted phenyl)thiazole ligands with with Bis(benzonitrile)palladium(II) dichloride in chloroform solvent at molar ratio Pd:L=1:2. The resulting complexes were characterized by the magnetic susceptibility, conductivity measurements, infrared, 1H NMR and the thermo gravimetric analysis. Elemental analyses, spectroscopic and another physical studies of the prepared palladium (II) complexes allowed structures to be proposed. The thermal properties of the prepared complexes indicated the all-decomposition steps and gave an insight about the stability of palladium(II) complexes. The physical analysis indicated that prepared ligands behaved as mono dental, bounding Pd(II) through the nitrogen atoms from the thiazole ring.
