A polyoxometalate (POM) based on the assembly of [P5W30O110]15 ({P5W30}) units and copper ions, {(H5P5W30O110)2[(en)4Cu4(3-OH)3(-H2O)]2}[Cu(en)2]4[Cu(H2O)3]center dot 12H2O (en = ethylenediamine) (1), has been made under hydrothermal conditions and characterized by single-crystal X-ray diffraction (XRD), elemental analysis, IR spectroscopy, thermogravimetric analysis, and power XRD; saturated {P5W30} was used as the precursor to make the new POM. POM 1 is the first 3D {P5W30}-based POM linked by late transition metal copper complex ions, and it also features the rarely seen linkages of the saturated {P5W30} units and [Cu4(3-OH)3(-H2O)] ({Cu4}) clusters. In the structure of 1, the {P5W30} units and {Cu4} clusters are alternately linked to form dimeric units and are further connected by two kinds of [Cu(en)2]2+ complex bridges, which results in the 3D framework.
