In this article, potassium tetrachloroplatinate(II), K2PtCl4, has reacted with an organic ligand [L: Br(C6H4)2P(C6H5)2] and created the complex PtCl2L2 (yield= 87% and Melting point= 215-217°C), then this compound with different techniques including FT-IR, 1H, 31P, 13C and 195Pt-NMR spectroscopy have been identified. Spectral analysis showed that the desired complex was synthesized with trans structure. In the following, the catalytic activity of this compound has been investigated by performing Suzuki and Heck coupling reactions for various aryl halides under optimal conditions including temperature, type of solvent, type of base, different amounts of base and different amounts of catalyst. The obtained results have shown the remarkable catalytic activity of this complex for the synthesis of the expected products.
