In this paper the current examination was under taken to with a view analyze the conceivable complex arrangement of Sn(II) and Pb(II) metal salts of O–Nitrophenol, 2-4 dinitrophenol, 1-Nitroso-2-napthol and Hydroxy quinoline with thiosalicylic corrosive utilizing total ethanol as dissolvable. Coordination locales in our subsequent ligand are Oxygen and Sulfur particles and go about as a bidentate twofold confronted ligand. The main aim in the present investigation the preparation of Ligands, methods of metals (Sn and Pb) as well as theory of IR Spectro & copy.
