Solvothermal Syntheses and Characterization of Three One-dimension Cadmium Selenidoarsenates [Ni(1,2-dap)3][As2CdSe4], [Zn(1,2-dap)3][As2CdSe4] and [Ni(en)3][As2CdSe4]
Three new cadmium selenidoarsenates, [Ni(1,2-dap)3][As2CdSe4](1)(1,2-dap=1,2-diaminopropane), [Zn(1,2-dap)3][As2CdSe4](2) and [Ni(en)3][As2CdSe4](3)(en=ethylenediamine), were synthesized under solvothermal conditions. And they are isostructural and monoclinic crystalls. As seen from their structures, they exhibited one-dimensional(1D) chains composed of [As2CdSe4]2- anions and [TM(amine)3]2+(TM=Ni, Zn; amine=1,2-dap, en) cations. Their absorption edges are 2.32, 1.84 and 2.38 e V, and they show the properties of the semiconductor. These compounds were also characterized by means of single-crystal X-ray diffraction(XRD), powder X-ray diffraction (PXRD), solid-state optical absorption spectrometry, and so on.
