Abstract

Abstract: Two new multi-copper-containing polyoxotungstate [Cu(en)2]6[Cu4(SiW9O34)2] 7H2O (1) and [Cu(en)2H2O]2[Cu(en)2]4[CuSiW11O39]2 7H2O (2) have been hydrothermally synthesized. The diffraction analysis reveals that the compound 1 represents the organic-inorganic hybrid based on the sandwish-type polyoxometalates linked by transition-metal coordination cations. The framework of 2 is a two-dimensional net-texture structure with vacancies in it, and the 2D layers are arranged in a parallelstaggering fashion to form a 3D supermolecules framework. It represents a 3D organic–inorganic hybrid based on the bimolecular Keggin polyoxometalates.

Key words: Polyoxometalate, Crystal structure, Electrochemistry
