利用水热合成法制备了一种新的沙漏型砷钼酸盐化合物(NH_1)_7[AsMo_8O_(30)](1),借助X射线单晶衍射、X射线粉末衍射、红外光谱(IR)、紫外光谱(UV)和热分析研究了化合物的结构和性质.结果表明,化合物1属于正交晶系,Cmcm空间群,晶胞参数为:a=0.848 3(4)nm,b=2.322 3(10)nm,c=1.559 1(7)nm,V=3.071(2)nm~3,Z=4,R_1[I>2σ(I)]=0.0431,ωR_2[I>2σ(I)]=0.123 6.X射线单晶衍射分析结果表明,化合物1包含沙漏型的砷钼酸盐阴离子[AsMo_9O_(30)]~(7-).
A new hourglass arsenomolybdate compound (NH_1) _7 [AsMo_8O_ (30)] (1) was prepared by hydrothermal synthesis method and characterized by X-ray single crystal diffraction, XRD, IR, The structure and properties of the compounds were studied by UV and thermal analysis. The results showed that compound 1 belongs to the orthorhombic, Cmcm space group with unit cell parameters of a = 0.848 3 (4) nm and b = 2.322 3 ( (2) nm = 3, Z = 4, R_1 [I> 2σ (I)] = 0.0431, ωR_2 [I> 2σ (I)] = 0.123 X-ray single crystal diffraction analysis showed that compound 1 contained hourglass arsenomolybdate anions [AsMo_9O_ (30)] ~ (7-).
