A new α-Keggin type polyoxometalate coordinated to four silver complex moieties: {PW9V3O40[Ag(2,2′-bipy)]2[Ag2(2,2′-bipy)3]2}

Abstract

A new polyoxometalate derivative {PW₉V₃O₄₀[Ag(2,2′-bipy)]₂[Ag₂(2,2′-bipy)₃]₂} 1 has been hydrothermally synthesized and structurally characterized by the single crystal X-ray diffraction. X-Ray analysis showed that both [Ag(2,2′-bipy)]⁺ and [Ag₂(2,2′-bipy)₃]²⁺ units are supported on the α-Keggin polyoxoanion [PW₉V₃O₄₀]⁶⁻via the surface bridging oxygen atoms. 1 represents the first α-Keggin type polyoxoanion coordinated with four transition metal complex moieties, which further acts as a neutral molecular units for the construction of an interesting three-dimensional supramolecular framework.
