A mono-cobalt substituted Wells-Dawson polyoxometalate with an antenna ligand linked to the Coll atom, was prepared by reaction of the mono-vacant Wells-Dawson precursor [P(2)W(17)O(6)](10-) with a imidazole-cobalt complex by using the bench method. It was isolated as the imidazole salt: (HIm)(7)H[P(2)W(17)O(61)Co(Im)]center dot 4H(2)O (1) (Im = imidazole). Compound I was characterized by elemental analysis, IR and UV/Vis spectroscopy, TG analysis, cyclic voltammetry and single-crystal/powder X-ray diffraction. This is the first example of the 3d transition metal mono-substituted Wells-Dawson polyoxometalate with an antenna ligand.
