Two novel inorganic-organic hybrids based on saturated Wells-Dawson polyoxoanion and copper-organonitrogen coordination polymer

Two novel compounds based on saturated Wells-Dawson polyoxometalate and copper-organonitrogen coordination polymer, (NH4)(3)(4,4'-H(2)bipy)[Cu-I(4,4'-bipy)](7)[P2W18O62](2)center dot 10H(2)O 1 and [Cu-II(en)(2,2'-bipy)](3)[P2W18O62]center dot 3H(2)O 2 (en=ethylenediamine, bipy=bipyridine), have been hydrothermally synthesized. The structure of 1 represents the first 2-D network consisted of saturated Wells-Dawson polyoxoanions and transition-metal coordination polymers. Compound 2 is a novel Wells-Dawson polyoxoanion supported by two copper(II) complex fragments with mixed en and 2,2'-bipy ligands in a single W3O13 triplet. (c) 2006 Elsevier B.V. All rights reserved.
