摘要：
A novel germanotungstate derivative based on the dysprosium cation and monovacant Keggin anion, [Cu(en)(2)](2)[Cu(en)(2)(H2O)](2)H-3{[Cu(en)(2)](2)[Na-2(H2O)(1.75)][K(H2O)(3)][Dy-2(H2O)(2)(GeW11O39)(3)]} center dot 6H(2)O(en = ethylenediamine) 1, has been synthesized by hydrothermal method and characterized by elemental analysis, IR-UV spectroscopy, thermal analysis and single-crystal X-ray diffraction. In the compound, one kind of clusters with theDy(3+)/[GeW11O39](8-) ratio of 2:3 was observed. Especially, the 2:3 type displays the novel cluster based on the rare earth and monolacunary Keggin polyoxometalate.
