Three new organic-inorganic hybrid compounds constructed from Keggin-type polyanions and transition metal complexes, [Mn(2,2'-bipy)(3)](1.5)[BW12O40Mn(2,2'-bipy)(2)(H2O)]center dot 0.25H(2)O (1), [Fe(2,2'-bipy)(3)](1.5)[BW12O40Fe(2,2'-bipy)(2)(H2O)]center dot 0.5H(2)O (2) and [Cu-2(phen)(2)(OH)(2)](2)H[Cu(H2O)(2){BW12O40Cu0.75(phen)(H2O)center dot 1.5H(2)O (3), have been hydrothermally synthesized and characterized by elemental analyses, IR, TGA and single-crystal X-ray diffraction. Compound 1 and 2 are isostructural and both exhibit monosupporting polyoxometalate cluster structure, each of which contains a [BW12O40](5-) cluster decorated by one transition metal complex. Compound 3 contains a bisupporting polyoxometalate cluster anion where two {Cu-0.75(phen)(H2O)}(0.75+) fragments are supported on the polyoxometalate dimer {Cu(H2O)(2)(BW12O40)(2)}(8-), this represents the first bisupporting polyoxometalate cluster based on a Keggin-type polyoxometalate dimer, which are further packed together via pi-pi stacking contacts into art extended 1-D chain.
