摘要：
A new polyoxometalate-based 4d-4f heterometallic compound, [{Ag-3(H2O)(2)}{Ce-2(H2O)(12)}H-5 subset of{H2W11Ce(H2O)(4)O-39}(2)]center dot 8H(2)O (1), has been synthesized and characterized by routine methods. In 1, the dimers constructed by two monosubstituted alpha-metatungstate [H2W11{Ce(H2O)(4)}O-39](7-) (simplified as {W11Ce17-} units are linked by Ce-III and Ag-I to form two-dimensional (2D) networks, and these networks are further connected by Ag-I-Ag-I ({Ag-2}(2+)) bonds to obtain a purely inorganic three-dimensional (3D) framework with two kinds of channels along the [1 0 0] and [0 1 0] directions. Furthermore, 1 exhibits reversible water sorption capability.
