| Abstract: | A 65·8 CdSO4-like 3-D framework Cu(en)2]3α-AsW11NaO39]·2H2O (1) constructed by monosodium-substituted Keggin arsenotungstates and copper(II)-ethylenediamine complexes (en = ethylenediamine) has been synthesized by reaction of Na8α-HAsW9O34]·11H2O, CuCl2·2H2O and ethylenediamine under hydrothermal conditions and structurally characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. Crystal data for 1: C12H52AsCu3N12NaO41W11, monoclinic, Cc, a = 20.409(9) Å, b = 16.737(8) Å, c = 16.561(7) Å, β = 104.607(7)°, V = 5474(4) Å3, T = 296(2) K; Z = 4, μ = 24.860 mm−1, GOOF = 1.086, R1 = 0.0284, wR2 = 0.0759. To the best of our knowledge, 1 represents the first 65·8 CdSO4-like 3-D monovacant Keggin arsenotungstate derivative in polyoxometalate chemistry. |
