摘要
采用溶剂热法合成了一种新的硒代锡酸盐Cd(tren)Sn Se_3(tren=三(2-氨乙基)胺)。单晶X-射线衍射分析表明该化合物为三斜晶系,空间群为P-1,a=0.7752(3)nm,b=0.8128(2)nm,c=1.2467(4)nm,α=97.299(19)°,β=103.639(18)°,γ=107.325(17)°,V=0.7121(4)nm3,Z=2,Dc=2.865 Mg·m-3,Mr=614.21,F(000)=564。该化合物为零维簇状结构,是由[Sn2Se6]单元的反式末端Se原子连接两个[Cd(tren)]2+单元形成的。紫外-可见漫反射光谱研究结果表明,该化合物的禁带宽度为1.80 e V。
A new selenidostannate Cd (tren) SnSe3 ( tren = tris (2-aminoethyl) amine ) was synthesized by solvothermal method. The single crystal X-ray diffraction analysis show that the compound crystallizes in the triclinic, space group P-1, with a =0.7752(3) nm, b =0.8128(2) nm, c = 1.2467(4) nm, a = 97.299(19)°, β = 103. 639(18)°, γ = 107. 325(17)°, V=0.7121(4) nm3, Z=2, Dc =2.865 Mg·m^-3 , Mr =614.21, F(000) =564. The compound is a zero-dimensional cluster structure and is formed by connecting two [ Cd (tren) ] 2 + units from the trans-terminal Se atoms of the [ Sn2Se6 ] unit. The results of UV-Vis diffuse reflectance spectra show that the band gap of the compound is 1.80 eV. Key words: selenidostannate ; solvothermal method ; crystal structure
