摘要
[Me4N]10[Fe4(OH)4(PW10O37)2] · 15H2O was synthesized by the reaction of FeCl3 ·6H2O, with △-Na8HPW9O34 and Me4NBr. Crystal data: M = 6225.75, space group P21/c with the monoclinic parameters: a = 1.3228(5), b = 3.5634(3), c = 1.5226(2) nm, β = 94.20(2)°, V = 7.1576nm3, 7 = 2,DC = 2.888 g/cm3, Mo Kαradiation (λ = 0.071069 nm), μ= 168.534 cm-1, F(000)=5576, final R = 0.0428 and Rw = 0.1204 for 7086 observed reflections with I > 2σ( I) . The structure of the title compound is the first structurally characterized heteropolymetalate with hydroxo-bridging metal aggregation Fe4OH4 encapsulated in the dimer of Keggin polyoxoanion.
