| Abstract: | Three novel scandium-containing heteropolytungstatesSc3(H2O)3NO3(PW9O34)2]10-(1a),Sc8(H2O)2(GeW9O34)2(GeW6O26)2]12-(2a) andSc11(W6O10)2(OH)2(H2O)16(BiW9O33)6]27-(3a) were synthesized by reactions of ScIII ions with trilacunary Keggin precursors,A-α-XW9O34]n-(X=P, Ge, n=9, 10) orB-α-BiW9O33]9-, in NaOAc/HOAc buffer solution under conventional synthetic condition, respectively. All the three compounds were characterized by means of single-crystal X-ray diffraction(XRD), Fourier transform-infrared(FTIR) spectroscopy ultraviolet-visible(UV-Vis) spectroscopy, elemental analysis, and thermogravimetric analysis. The aqueous solution stability of the sandwich polyanionSc3(H2O)3NO3(PW9O34)2]10- was also verified by electrospray ionization mass spectrometry(ESI-MS) due to its good solubility in water. |
