چکیده مقاله:

Organometallic compounds containing metal-carbon bonds have many applications in biochemistry. One of the most important elements in organometallic chemistry is platinum, because it makes a wide range of organometallic compounds that are kinetically inert to provide them to be isolated and characterized. The importance of platinum(II) and palladium(II) complexes with square-planar geometry have been increased after finding of the anti-tumor activity of cis-dichlorodiammineplatinum(II) [1]. Also, organoplatinum complexes are oxidized or reduced easily by two-electron transfer between the two essential oxidation states and so the oxidative addition and reductive elimination reactions perform easily in these complexes. Since, the main geometry for +2 and +4 oxidation state are square planar and octahedral, respectively [2]. In this research, we reported synthesis and structural characterization of a new arylplatinum (II) complex containing N2S2 donor atoms. In order to synthesize of this complex, [(p-MeC6H4)2Pt (SMe2)2] was used as starting material and was synthesized by the reaction of [PtCl2 (SMe2)2] and para-tolyllithium. The new platinum complex containing N2S2 chelating ligand was synthesized by the reaction of cis-[Pt (p-MeC6H4)2(SMe2)2] and chelating ligand in a 1:1 molar ratio. This reaction was performed in chloroform and stirred for 72 h. Then the solvent was evaporated and an orange precipitate obtained and washed with n-hexane and diethylether. The complex was characterized by FT-IR, 1H NMR, UV-Vis spectroscopies, elemental analysis and molar conductance. Emission behavior of this complex was studied by fluorescence spectroscopy.
