Three novel supramolecular hybrid compounds based on keggin polytungstates

Abstract

Three novel supramolecular compounds [PWVI10.5WV1.5O40][Cu(2, 2′-bpy)2]4.5 (1), [CuI(Phen)2]4[CuI5Cl4(Phen)4][PWVI10WV2O40]2·4H2O(2) and [CuI(Phen)2]4[CuI5Cl4(Phen)4][BWVI12O40]2·2H2O(3) (bpy = bipyridine, Phen = 1,10-Phenanthroline) have been synthesized and characterized by IR, UV-Vis, TG, XRD, elemental analyses and single crystal X-ray diffraction analyses. Compound 1 is the first example of a hybrid compound which is constructed from polyoxometalates and supramolecular noncovalent coordination cages. Both compounds 2 and 3 are constructed from two different types of building blocks: polyoxometalates and metal halide fragments.
