A polyoxoanion with an unusual[Sb6O16(OH)12]cluster skeleton and S4 molecular symmetry[Mo4Sb6(OH)12O24]~(6-)

摘要

A rich antimony polyoxoanion[Mo4Sb6(OH)12O24]~(6-)was crystallized as potassium salt in neutral aqueous solution and characterized by IR,UV-vis spectra,CVs and single crystal X-ray diffraction.X-ray structural analysis shows that the polyanion[Mo4Sb6(OH)12O24]~(6-)has S4 molecular symmetry and a ellipsoid-shape structure built of an unusual[Sb6O16(OH)12]framework capped with four segregated{MoO2}groups.
