Sodium Ion-linked Waugh Polyanion with a 4,4-Connected Layered Structure

摘要

A new polyoxometalate compound formulated as Na2(C3H5N2)4[MnMo9O32]-2H2O 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum and single-crystal X-ray diffraction.The title compound crystallizes in the monoclinic system, space group C2/c, with a = 16.076(2), b = 14.6488(19), c = 18.767(2) -, β = 108.6030(10)o, V = 4188.6(9) -3, C12H24MnMo9N8Na2O34, Mr = 1788.77, Dc = 2.837 g/cm3, μ(MoKα) = 3.024 mm(1, F(000) = 3396, Z = 4, the final R = 0.0270 and wR = 0.0605 for 3829 observed reflections (I > 2((I)).
