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.
