摘　　要：通过水热法合成了一个由[As^ⅤMo10O36]^9-片段和四个过渡金属配合物构筑而成的结构新颖的杂多钼酸盐[Ni(dien)]4H[As^ⅤMo^Ⅴ2Mo^Ⅵ8O36]·9H2O (1)(dien=diethylenetriamine),通过元素分析、红外光谱和X射线单晶衍射对其进行了表征.1具有少见的篮状缺位结构,是通过除去Keggin型结构上的两个共边MoO6八面体而构成的.One novel heteropolymolybdate,[Ni(dien)]4H[As^ⅤMo2^ⅤMo8^ⅥO36]·9H2O(1)(dien=diethylenetriamine),constructed from the new fragment[As^ⅤMo10O36]^9-and four transition metal complexes has been synthesized under the hydrothermal condition and characterized by the elemental analysis,IR spectroscopy and single-crystal X-ray diffraction.Structurally 1 resembles an infrequent lacunary structure like an open basket,which derives from the famous Keggin structure by removing two edge-sharing MoO6 octahedra.
