چکیده مقاله:
Metal clusters occupy a prominent position in chemistry. In addition to the interest arising from the potential utility of metal clusters in catalysis and the preparation of newmaterials, there has also been significant interest in exploiting the remarkable structural and bonding properties of these compounds. Metal-metal dative bonds play an important role in the synthesis of metal clusters, and electron-rich Platinum(II) complexes can expand opportunities for the formation of metal-metal dative bonds ¹. In this work, the tetranuclear Pt(Ⅱ)-Ag(Ⅰ) cluster {Pt₂Ag₂[(μ-PPh)₂Py]( μ- Cl)₂(bhq)₂}(OTf)₂ has been prepared by reaction of AgOTf , 2,6- (bisdiphenylphosphino)prydine and Pt[(bhq)(SMe₂)Cl] in 1:1:1 molar ratio. The structure of the cluster is determined using ³¹PNMR and ¹HNMR spectroscopy and its crystal structure was further determined by X-ray crystallography [Fig1.]. This cluster shows yellow emission in solid state.
