【Abstract】 A new polyoxometalate [PW12O40][NH3(CH)6NH2]3·4H2O 1 is hydrothermally synthesized and characterized by IR, elemental analyses, X-ray photoelectron spectrum, ESR and Single crystal X-ray diffraction. The title compound is a supramolecular compound constructed from Keggin polyoxoanions with phosphorus-centered and 1,6-diaminohexane through hydrogen bonds. The anion [PW12O40]3- is composed of a disordered PO4 tetrahedron surrounded by four vertex-sharing W3O13 triads which result from the association of three edge-sharing WO6 octahedra. The photoluminescence experiment indicates that Compound 1 exhibits strong fluorescent emission and may be an excellent candidate for potential photoactive materials.更多还原
