摘　　要：A new heteropolytungstate, [H2bpy]3[SiMnW11O39]· 1.25H2O （1）, has been prepared under mild hydrothermal conditions and structurally characterized by single crystal X-ray diffraction. It is the first characterized compound containing ID zigzag chain of transition metal substituted Keggin heteropolytungstate, which is connected through a common oxygen atom. The elemental analysis and IR of it are also described.A new heteropolytungstate, [H2bpy]3[SiMnW11O39]· 1.25H2O （1）, has been prepared under mild hydrothermal conditions and structurally characterized by single crystal X-ray diffraction.
