摘      要：A 1D chain-like organic-inorganic hybrid rare earth derivative of polyoxometalate H0.5[Sm（H2O）6]0.25[Sm（H2O）5]0.25{[Sm（H2O）7][Sm（H2O）2（DMSO）][SiW11O39]}·4.5H2O has been firstly synthesized by reaction of α-K8SiW11O39.13H2O, HClO4, Sm2O3 with dimethyl sulfoxide （DMSO） and characterized by elemental analysis, IR spectra and single crystal X-ray diffraction. The neighboring polyanionic units {[Sm（H2O）7][Sm（H2O）2（DMSO）][SiWHO39]}^2- are bridged together to a 1D chain structure by means of [Sm（H2O）2（DMSO）]^3＋ ion.
