Novel mercury(II) complexes of Schiff base ligands: Synthesis and spectral characterization

The synthesis and characterization of mercury(II) complexes with Schiff base ligands, [Hg(L)2]Cl2 (L1=Acetic acid (2,4-Dichloro-benzylidene)-hydrazide and L2=Acetic acid (3- Nitro-benzyliden)-hydrazide) are described. Vibrational study in the solid state of hydrazide derivatives and its new mercury(II) complexes was performed by 1H-NMR, IR spectroscopy, UV spectral techniques. The changes observed between the FT-IR and UV-Vis spectra of the ligands and of the complexes allowed us to stablish the coordination mode of the metal in complexes. The results suggest that the Schiff bases coordinate as univalent anions with their twodentate N, O donors derived from the carbonyl and azomethine nitrogen
