چکیده
|
The new trans-[pt(4-mpy)2cl4] (1) complex (4-mpy is 4-methylpyridine) was prepared from the reaction of h2ptcl6.6h2o with 4methylpyridine in methanol. synthesized complex was thoroughly characterized by elemental analysis, ir and 1hnmr spectroscopy.elemental analysis data (c, h, n) support the general composition of the title complex and the structure have been established by singlecrystal xray diffraction study. in this complex the geometry platinum(iv)cation is octahedral, formed by two nitrogen atoms from two 4mpy ligands and four chloride anions. also, in this complex the strong π…π interactions between pyridine rings are effective on the stabilization of the crystal packing. furthermore, the luminescence properties of the free 4mpy ligand as well as the complex 1were investigated in solution. luminescence emission of complex 1 was red shifted and is weaker than that of the free 4mpy ligand.

Abstract
|
The new trans[Pt(4mpy)2Cl4] (1) complex (4mpy is 4methylpyridine) was prepared from the reaction of H2PtCl6.6H2O with 4methylpyridine in methanol. Synthesized complex was thoroughly characterized by elemental analysis, IR and 1HNMR spectroscopy.Elemental analysis data (C, H, N) support the general composition of the title complex and the structure have been established by singlecrystal Xray diffraction study. In this complex the geometry platinum(IV)cation is octahedral, formed by two nitrogen atoms from two 4mpy ligands and four chloride anions. Also, in this complex the strong π…π interactions between pyridine rings are effective on the stabilization of the crystal packing. Furthermore, the luminescence properties of the free 4mpy ligand as well as the complex 1were investigated in solution. Luminescence emission of complex 1 was red shifted and is weaker than that of the free 4mpy ligand.
