| Abstract: Heteropolytungstates α，β-［(RSn)3GeW9O37］·nH2O (M=Bu4N+, Me4N+; R=Bu, Ph) have been prepared and characterized by elemental analysis, IR, UV spectroscopy, 1H, 119Sn and 183W NMR, Polarography and Time of Flight (TOF) mass spectroscopy. 183W NMR of the title anion indicates the new complexes have Keggin structure with three substituted (RSn)3+ groups occupying the vacant sites in a triad of corner-sharing RSnO6 octahedron. The TOF spectra show the title anions exist as monomers. Catalytic activity of the title anions for olefin epoxidation is also survied. |
