A new Keggin-type 3d–4f heterometallic incorporated polyoxotungstate, {[Cu(en)2(H2O)][DyCu3(en)3(OH)3(H2O)2(GeW11O39)]}2·18H2O (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)3O} cubane fragments and represents the first tungstogermanate with heterometallic 3d–4f cubane cluster.
Graphical Abstract
A new Keggin-type 3d–4f heterometallic polyoxotungstate {[Cu(en)2(H2O)] [DyCu3(en)3(OH)3(H2O)2(GeW11O39)]}2·18H2O (en = ethylenediamine) (1) has been synthesized under hydrothermal conditions. The dimeric compound 1 represents the first tungstogermanate containing {DyCu3(OH)3O} cubane cluster.
