摘　　要：在水相中合成了一例新的夹心型含锰铋钨酸盐Na_(9)H[(Mn(H_(2)O)_(3))_(2)(Mn(H_(2)O)_(2))(WO_(2))(BiW_(9)O_(33))_(2)]·30H_(2)O(1)。通过元素分析、紫外光谱、红外光谱、粉末X射线衍射、单晶X射线衍射和热重分析对其进行了结构表征。单晶结构分析表明化合物1中的阴离子是由2个三缺位Keggin型β⁃B⁃[BiW_(9)O_(33)]^(9-)阴离子内、外连接2个[(Mn(H_(2)O)_(2))0.5(WO_(2))0.5]^(2+)配阳离子和2个[Mn(H_(2)O)_(3)]^(2+)亚单元组成。磁学性质研究表明在化合物1中锰离子之间存在反铁磁耦合作用。A new sandwich⁃type tungstobismuthate containing manganese􀃭,Na_(9)H[(Mn(H_(2)O)_(3))_(2)(Mn(H_(2)O)_(2))(WO_(2))(BiW_(9)O_(33))_(2)]·30H_(2)O(1),has been synthesized in the aqueous solutions and structurally characterized by elemental analyses,UV⁃Vis spectroscopy,IR spectroscopy,powder X⁃ray diffraction,single⁃crystal X⁃ray diffraction and ther⁃mogravimetric analysis.Single crystal X⁃ray analysis shows that the polyanion of 1 is composed of two trivacantβ⁃B⁃[BiW_(9)O_(33)]^(9-)Keggin fragments joined together by two[(Mn(H_(2)O)_(2))_(0.5)(WO_(2))_(0.5)]^(2+)moieties and two[Mn(H_(2)O)_(3)]^(2+)subunits located in the inner and outer positions,respectively.Magnetic measurements indicate that 1 exhibits the antiferro⁃magnetic couplings between Mn􀃭centers.CCDC:2141242.
