摘　　要：在浓氢碘酸水溶液中,顺式和反式-1,2-环己二胺(DAC)分别与三碘化锑反应得到2种有机-无机杂化异构体(cis-1,2-DACH_2)[SbI_5]·H_2O(1)和{(trans-1,2-DACH_2)[SbI_5]·H_2O}_n(2)。X射线单晶衍射表明化合物1中的无机成分是由2个[SbI_6]八面体通过共I-I边形成的二聚体[Sb_2I_(10)],而化合物2中的无机部分是[SbI_6]八面体通过共享顶点形成的一维锯齿链。此外,利用紫外-可见光谱、荧光光谱和密度泛函理论对化合物1和2进行了比较研究。Reactions of cis- and trans-1,2-cyclohexanediamine (DAC) with antimony iodide in concentrated HI aqueous solution afforded two organic-inorganic hybrid isomers (cis-1,2-DACH2)[SbI5]·H2O (1) and {(trans-1,2- DACH2)[SbI5]·H2O}n (2), respectively. The single-crystal X-ray diffraction revealed that the inorganic component in compound 1 is a dimer [Sb2I10] built up from two [SbI6] octahedra by sharing I-I edge, and that in compound 2 is a zigzag chain constructed with corner-sharing octahedral [SbI6] units. In addition, both compounds have been investigated and compared by UV-Vis, fluorescent spectra, and DFT calculation. CCDC: 1818719, 1;1818718, 2.
