摘　　要：水热合成了一种新的1-D链状四帽pseudo-Keggin结构钼钒簇合物[Ni(enMe)_(2)]_(2)-[Ni(enMe)_(2){H Mo^(VI)_(4)Mo^(V)_(4)V^(IV)_(8)O_(40)(V^(V)O_(4))}]4H_(2)O 1,X-射线单晶结构分析表明,该晶体属单斜晶系,C2/c空间群。晶体学参数为a=26.3006(6),b=13.6195(3),c=19.7122(5),b=105.8330(10),V=6793.0(3)Å,Z=4,Dc=2.566 g/cm^(3),Mr=2623.96,m=3.507 mm-1,F(000)=5088,R=0.0700,wR=0.1529,S=1.019。该簇合物是由金属配位桥Ni(enMe)_(2)桥联四帽pseudo-Keggin结构{HMo^(VI)_(4)Mo^(V)_(4)V^(IV)_(8)O_(40)(V^(V)O_(4))}簇构成一维链状结构,链与链间通过与另外一个配位阳离子[Ni(enMe)_(2)]^(2+)的氢键相互作用构成超分子网状结构。The novel polyoxometalate,[Ni(enMe)_(2)]_(2)[Ni(enMe)_(2){HMo^(VI)_(4)Mo^(V)_(4)V^(IV)_(8)O_(40)(V^(V)O_(4))}]4H_(2)O,was synthesized and characterized by elementary analysis,IR spectra and X-ray diffraction.The compound crystallizes in monoclinic,space group C2/c with a=26.3006(6),b=13.6195(3),c=19.7122(5)Åb=105.8330(10),V=6793.0(3)Å,Z=4,Dc=2.566 g/cm^(3),Mr=2623.96,m=3.507 mm^(-1),F(000)=5088,R=0.0699,wR=0.1526 and S=1.018.The compound consists of infinite chains of[Ni(enMe)_(2)]_(2)[Ni(enMe)_(2){HMo^(VI)_(4)Mo^(V)_(4)V^(IV)_(8)O_(40)(V^(V)O_(4))}]4H_(2)O clusters covalently linked through[Ni(enMe)_(2)]group and another isolated[Ni(enMe)_(2)]^(2+)cations,occupying the interchain regions and providing charge compensation.
