Synthesis and Characterization of New Mercury (II) Complexes with Bidentate Chelating Schiff Base Iminopyridine Ligand

First, schiff base iminopyridine ligands has been prepared by the condensation between primary amines, different substituted anilines and active carbonyl group of pyridine carboxaldehyde, then the complexes [diiodo (3-ethylphenyl) pyridine-2-yl methylene amine] mercury(ii), complex a, [dibromo (2,5-dimethylphenyl) pyridine-2-yl methylene amine] mercury(ii) complex b, and [dinitrato bis-(2,6-dimethylphenyl) pyridine-2-yl methylene amine] mercury(ii) nitrate, complex c, synthesized in methanol solution. the ligands and metal complexes have been characterized by elemental analysis, uv, ir, 1h-nmr and 13c-nmr spectroscopy. the spectroscopic data of metal complexes indicated that the metal ions are complexed with azomethine group and pyridine nitrogen atoms. the schiff base ligand acts as bidentate with two n sites and can coordinate with mercury ion.
