Spectroscopic, Thermal and Structural Studies of a New Mercury(II) Complex of 4ʹ-(4-Pyridyl)-2,2ʹ:6ʹ,2ʹʹ-terpyridine (Pyterpy) Ligand, [Hg (Hpyterpy)(SCN)2]2(MeSO4)2

A new mercury(II) complex [Hg(Hpyterpy)(SCN)2]2(MeSO4)2 was prepared from the reaction of 4ʹ-(4-pyridyl)-2,2ʹ:6ʹ,2ʹʹ-terpyridine (pyterpy), as a polypyridyl ligand, with mercury(II) thiocyanate. The compound was characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy and its structure was determined by X-ray single-crystal diffraction. The thermal stability of compound was studied by thermogravimetric (TG) and differential thermal analyses (DTA).
