| 摘 要： | 在常温水溶液条件下,合成了一种二维四核铁取代夹心型锑钨酸盐NdNa3Fe4(H2O)10]β-B-SbW9O33]2·36H2O(1),并通过IR光谱和单晶X射线衍射对其进行了表征.化合物1属于三斜晶系,P-1空间群,晶胞参数:a=1.264 8(3)nm,b=1.270 1(3)nm,c=1.616 0(4)nm,α=74.467(4)°,β=77.592(4)°,γ=83.658(4)°,V=2.438 9(9)nm3,Z=1,Dc=4.000g/cm3,GOOF=1.047,R1=0.065 6,wR2=0.162 2.X射线单晶结构分析表明,化合物1的多阴离子由两个相同的三缺位Kegginβ-B-SbW9O33]9-单元通过四个八面体配位的铁离子连接而成.四个FeO6八面体没有直接相连,四个FeIII离子可以分为两组:内部的FeIII离子带有两个水配体,而外部的FeIII离子连有三个水配体.邻近二聚多阴离子通过无序的钠/钕桥配离子构筑了二维层结构.

| Abstract: | A 2-D tetra-FeIII substituted sandwich-type antimonotungstate NdNa3Fe4（H2O）10]β-SbW9O33]2·36H2O（1） was prepared under the conventional aqueous solution condition and characterized by IR spectrum and single-crystal X-ray diffraction. I crystallizes in the triclinic space group P-1 with a = 1.264 8（3） nm, b = 1.270 1（3） rim, c = 1.616 0（4） nm, α=74.467（4）°,β=77.592（4）°,γ=83.658（4）°,V=2.4389（9）nm3,Z=1,Dc=4.000g/cm3,G00F-1.047,R1=0.0656,wR2=0.1622. X-ray structure analysis reveals that 1 contains a dimeric polyoxoanion constructed from two identical trivacant Keggin β-B-SbW9O38]9- units linked via four octahedral FeIII cations. There is no direct connection among four FeO6 octahedra. Four FeIII cations can be divided into two inequivalent pairs： the inner Fem cations have two terminal water ligands while the outer FenI cations own three terminal water ligands. Adjacent dimeric polyoxoanions are connected together through disordered Na/Nd bridges giving rise to a 2-D sheet structure. |
