摘要：
A new Keggin-type 3d-4f heterometallic incorporated polyoxotungstate, {[Cu(en)(2)(H2O)][DyCu3(en)(3)(OH)(3)(H2O)(2)(GeW11O39)]}(2)center dot 18H(2)O (1) (en = ethylenediamine), has been hydrothermally synthesized and characterized by IR spectroscopy, TG, and single-crystal X-ray diffraction. Structure analysis revealed that the dimeric compound 1 contains {DyCu3(OH)(3)O} cubane fragments and represents the first tungstogermanate with heterometallic 3d-4f cubane cluster.
