Synthesis, characterization and thermal analysis of Hg(II) complexes with hydrazide ligands

A number of new complexes have been synthesis by reaction of novel ligands Acetic acid (2- Hydroxy-benzyliden)-hydrazide (L1), Acetic acid (3-phenyl-allylidene)-hydrazide (L2) with mercury(II) halide. These new complexes were characterized by elemental analysis, IR spectroscopy and UV spectral techniques. The changes observed between the FT-IR and UV-Vis spectra of the ligands and of the complexes allowed us to establish the coordination mode of the metal in complexes. Thermal properties, TG-DTA of these complexes were studied too. TG- DTA and other analytical methods have been applied to the investigation of the thermal behavior and structure of the compounds [Hg(L)2]Cl2. Thermal decomposition of these compounds is multistage processes
