摘　　要：The heteropolytungstate Na9[{Na(H2O)2}3{Cu(H2O)}3(BiW9O33)2]?2H2O is obtained by the reaction of Na2WO4·2H2O, Bi(NO3)3·5H2O with CuCl2·2H2O at pH≈6. The structure and chemical composition are de-termined by X-ray diffraction analysis and elemental analysis. The crystal data and main structure refinement are: a=1.410(3) nm, b=2.338(5) nm, c=3.173(6) nm, =98.06(4)? V=10.354(35) nm3, monoclinic crystal system, space group: C2/c, Z=4, R1=0.0471, wR2=0.0642 [I>2(I)], R1=0.1371, wR2=0.0868 (all data). [{Na(H2O)2}3{Cu(H2O)}3W9O33)2]9- has D3h symmetry. IR, UV-vis spectra, TG curve and magnetic property of the complex were also discussed. The compound exhibits an antiferromagnetic coupling with J=-8.08 cm-1 and g=2.21.The heteropolytungstate Na9[{Na(H2O)2}3{Cu(H2O)}3(BiW9O33)2]?2H2O is obtained by the reaction of Na2WO4·2H2O, Bi(NO3)3·5H2O with CuCl2·2H2O at pH≈6.
