Two new tungstogermanates K(2)Na(10)[Cu(4)(GeW(9)O(34))(2)] center dot 15.5H(2)O (1) and K(4)Na(6)[Cu(3.5)W(0.5)(H(2)O)(2)(GeW(9)O(34))(2)] center dot 17H(2)O (2) have been obtained by the conventional aqueous solution methods and characterized by IR, element analysis, electrochemistry and single-crystal X-ray analysis. Compound 1 is composed of the [Cu(4)(GeW(9)O(34))(2)](12-) anions linked by two equivalent bonds of Cu-O-W, representing the first one-dimensional chain-like structure based on sandwich-type polyoxometalates by direct condensation to form oxo-bridged arrays of clusters. Compound 2 is a sandwich structure, consisting of two trivacant [GeW(9)O(34)](10-) units linked by a [Cu(3.5)W(0.5)(H(2)O)(2)] cluster, and the anions are linked by the K(+) and Na(+) to form a three-dimensional structure.
