Synthesis, characterization and thermal studies of mixed ligand complexes of HG[II] thiosemicarbazones with 2-aminothiazole

Several Hg[II] mixed ligand complexes of thiosemicarbazones [2-acetylpyridine-, 4-aminoacetophenone- and 2-furaldehyde thiosemicarbazones] with 2-aminothiazole have been prepared. Structural investigations of the complexes have been made based on elemental analyses, spectral [UV-Vis, IR] studies and conductivity measurements. The JR. spectra indicated the bidentate [neutral] behaviour of the ligands. The thermogravimetry [TG], derivative thermogravimetry [DTG] and differential thermal analyses [DTA] have been used to study the thermal decomposition and kinetic parameters of the complexes using the Coasts-Redfern and Horowitz-Metzger equations
