The first PtIV-containing discrete polyoxoplatinate(II) [PtIVPtII6O6(AsO2(CH3)2)6]2–(Pt7) and polyoxopalladate(II) [PtIVPdII6O6(AsO2(CH3)2)6]2–(PtPd6) have been prepared and characterized in the solid state, in solution, and in the gas phase. The molecular structures of the noble metal-oxo clusters Pt7and PtPd6comprise a central, octahedral PtIVO6hetero group surrounded by six square-planar MO4(M = PtII, PdII) units, which are capped by six dimethylarsinate ligands. The polyanions were prepared under simple one-pot aqueous solution conditions by reacting H2Pt(OH)6with either K2PtCl4or Pd(NO3)2in sodium dimethylarsinate buffer (pH 7) at 80 °C. Catalytic studies were performed on Pt7supported on SBA15-apts for o-xylene hydrogenation at 300 °C and 90 bar H2pressure and indicated excellent activity and recyclability with low activation temperature. |
