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′-H2bipy)[CuI(4,4′-bipy)]7[P2W18O62]2·10H2O 1 and [CuII(en)(2,2′-bipy)]3[P2W18O62]·3H2O 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.
