摘　　要：在水热条件下,成功合成了一例新的过渡金属镍修饰的有机-无机杂化型三维超分子多酸化合物[Ni(en)2(H2O)2][Ni(en)3]2[Ni(en)2(H2O)]2[Ni4(α-PW9O34)2(H2O)2]·14H2O(1)(en=乙二胺),并通过元素分析、红外光谱、热分析和X射线单晶及粉末衍射对化合物进行了表征和研究.从超分子化学的角度来看,化合物1中的夹心型簇阴离子之间通过广泛的氢键作用,进而形成三维超分子网络结构.A new 3 D nickel-substituted organic-inorganic hybrid supramolecular polyoxometalate,[Ni（en）2（H2 O）2][Ni（en）3]2[Ni（en）2（H2 O） ]2[Ni4（α-PW9 O34）2（H2 O）2]·14 H2 O（ 1）（ en =C2 H8 N2）,has been prepared under hydrothermal conditions and characterized by elemental analysis,IR spectroscopy,XRD,thermogravimetric（ TG） analysis and X-ray single-crystal diffraction. From the viewpoint of supramolecular chemistry,the sandwich-type polyoxoanions in 1 are further extended to 3-D frameworks via extensive hydrogen-bonding interactions.
