摘要:

采用溶剂热法,在1,4-丁二胺中合成以碱金属为客体阳离子的硫属锡酸盐Cs8Mn4Sn4Se16(1)及1,2-丙二胺(1,2-dap)配位的过渡金属为客体阳离子的硫属锡酸盐[Ni(1,2-dap)3]2Cd2Sn2S8(2)。 并采用单晶X射线、紫外可见漫反射、热重分析-差示扫描量热分析(TG-DSC)等手段进行表征。 结果表明,化合物1为正交晶系,空间群为Fddd;化合物2为正交晶系,空间群为Cmcm;且结构中均包含SnQ4(Q=S,Se)四面体与TMQ4(TM=Mn,Cd)四面体通过共边而成的一维(1-D)阴离子链,紫外可见漫反射分析表明,化合物1、2的禁带宽度分别为1.70 和2.21 eV,具有半导体性质。 且TG-DSC测试显示化合物1、2在一定温度下具有一定的稳定性。

Abstract:

The chalcogenidostannate compound Cs8Mn4Sn4Se16(1) and [Ni(1,2-dap)3]2Cd2Sn2S8(2) were solvothermally synthesized by using the alkali metal in 1,4-butanediamine, and 1,2-propanediamine(1,2-dap) coordinated transition metal as guest cations, respectively. Single-crystal X-ray, ultraviolet-visible(UV-Vis) diffuse reflectance spectroscopy and thermogravimetric analysis and differential scanning calorimetry(TG-DSC) indicate that the compounds 1 and 2 belong to orthorhombic system Fddd group and Cmcm group. Both 1 and 2 consist of one-dimensional straight anionic chains composed of edge sharing tetrahedron SnQ4(Q=S, Se) or TMQ4(TM=Mn, Cd). The UV-visble diffuse reflectance data show that the band gaps of compounds 1 and 2 are 1.70 eV and 2.21 eV, respectively, which implies that compounds 1 and 2 have semiconductor properties. The TG-DSC results indicate good thermal stability of compunds 1 and 2 in some temperature condition.
