A novel two-dimensional solid, [{Cu(en)2}4(H4W12O42)]·9H2O (en = ethylenediamine), has been prepared under mild hydrothermal conditions. Single crystal X-ray diffraction revealed that each paradodecatungstate [H4W12O42]8− cluster in the title compound is connected with its four adjacent clusters through eight {Cu(en)2}2+ bridging groups into a two-dimensional layered structure. Its cyclic voltammetric behavior in aqueous electrolyte demonstrated that its modified carbon paste electrode has a good stability. A probe reaction indicated that the catalytic activity of paradodecatungstates in epoxidation of maleic anhydride has been enhanced by assembling paradodecatungstate clusters into extended structures.
