Abstract:
Two charge transfer heteropoly complexes,(C9H7N)4H3PMo6W6O40·9H2O(abbreviated PMo6W6-KL)and(C9H7N)5.5H5PMo10V2O40·5.5H2O·CH3CN(abbreviated PMo10V2-KL)have been prepared in aqueous solution from the electronic donor of quinoline and the electronic acceptor of molybdenum or vanadium substituted polyoxotungstates with Keggin structure, and characterized by elemental analysis, ICP, TGA, IR, UV, diffusion reflectance electronic spectra, XPS and ESR. The results show that the stronger interactions and charge transfer existing between donor and acceptor; meanwhile, V+5 and Mo+6 were deoxided to V+4 and Mo+5, respectively. The Keggin structure of the heteropoly anions was retained in charge transfer heteropoly complexes, but the characteristic vibrational bands have some red or blue shift.
