Department of Chemistry, Himachal Pradesh University, Summer Hill, Shimla- 171 005, Himachal Pradesh, India E-mail : scchaudhry@sancharnet.in Manuscript received 2 September 2008, accepted 26 February 2009 The dichloro bis(4-methoxyphenoxo)tin(IV) complex of composition SnCI2(OC6H4OMe-4)2 has been synthesized In quantitative yield by the reaction of tin tetrachloride with bimolar amount of 4-methoxyphenol in benzene under reflux and characterized by elemental analyses, molar conductance measurement molecular weight determination, IR, 1H NMR and FAR-mass spectral techniques. The thermal behaviour of the complex has been studied by TG-DTA techniques. The reactions of parent complex with nilrogenous bases viz. diethylamine, triethylamine, imidazole, benzimidazole (L), 2,2'-bipyridyl and 1,10-phenanthroline (B) yielded addition compounds of composition SnCl2(OC4H4OMe-4),2.L and SnCl2(OC6H4OMe-4)2.B characterized by physicochemical and IR spectral data
