Bivalent tin(II)-4-methoxyphenoxide of composition Sn(OC6H4OMe-4)2 (1) has been synthesized from the reaction of SnCl2 with bimolar amounts of 4-methoxyphenol and diethylamine in tetrahydrofuran and characterized by elemental analysis, molar conductance measurement and IR spectral studies. Thermal behaviour of the complex has been studied by TGA-DTA techniques. The reactivity of (1) with HgCl2 has been investigated using potentiometric and cyclic voltammetric technique. Conductometric titration of complex (1) with sodium salt of 4-methoxyphenol suggests the formation of double phenoxide of composition Na2[Sn(OC6H4OMe-4)4]. Addition compounds of composition Sn(OC6H4OMe-4)2ź2L and Sn(OC6H4OMe-4)2źB (L = diethylamine and pyridine; B= l,10-phenanthroline and 2,2'-bipyridyl) have also been prepared and characterized by physicochemical and IR spectral studies. The complex (1) has also been screened for its antifungal activity.
