bismuth(Ⅲ) heteropolymate%polyoxometalate%crystal structure
A Bi(Ⅲ) contained heteropolymate compound Na3H2[Ce3(H2O)18Bi2W22O76] (23H2O 1 has been synthesized. It crystallizes in the triclinic system, space group P with a = 14.370(3), b = 17.113(3), c = 24.764(5) A, α = 74.33(3), β = 77.20(3), γ = 65.29(3)o, V = 5285.3(18) A3, Z = 2, Mr = 6908.66, Dc = 4.341 g/cm3, F(000) = 6042, μ(MoKσ) = 28.543 mm-1, R = 0.0604 and wR = 0.1659 for 15788 reflections with I > 2σ(I). The structure analysis revealed that in the anionic framework of the title compound the [Bi2W22O76]14- anions are connected by Ce3+ and Na+ cations into a three dimensional network.
