Department of Chemistry, South Tehran Branch, Islamic Azad University, Tehran, Iran


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.
