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

Abstract

Two novel compounds based on saturated Wells–Dawson polyoxometalate and copper–organonitrogen coordination polymer, (NH 4) 3(4,4′-H 2bipy)[Cu I(4,4′-bipy)] 7[P 2W 18O 62] 2·10H 2O 1 and [Cu II(en)(2,2′-bipy)] 3[P 2W 18O 62]·3H 2O 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 W 3O 13 triplet.
