| Abstract: | Two new tungstogermanates K2Na10[Cu4(GeW9O34)2] · 15.5H2O (1) and K4Na6[Cu3.5W0.5(H2O)2(GeW9O34)2] · 17H2O (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 [Cu4(GeW9O34)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 [GeW9O34]10− units linked by a [Cu3.5W0.5(H2O)2] cluster, and the anions are linked by the K+ and Na+ to form a three-dimensional structure.
