摘　　要：Three novel scandium-containing heteropolytungstates[Sc3(H2O)3NO(PW9O34)2]^10(1a)Scs(H2O)2(GeW6O34)2(GeW6O26)2]^12(2a)and[Sc11(W6O10)2(OH)2(H2O)16(BiW9O33)6]^27(3a)were synthesized by reactions of Sclllions with trilacunary Keggin precursors,[A-a-XW9O34]^n(X=P,Ge,n=9,10)or[B-a-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 solutior stability of the sandwich polvanion[Sc3(H2O)3(pw9O34)2]^10-was also verified by electrospray ionization mass Spectrometry(ESI-MS)due to its good solubility in water.
