采用溶剂热方法合成了3个多元硫属化合物[Mn(1,2-dap)2(H2O)]2(μ-Sn2Q6)(Q=S(1)和Se(2))和[Mn(tren)]2(μ-Sn2S6)(3),用X-射线单晶衍射测定了化合物的结构,并通过红外光谱、紫外-可见漫反射光谱对其进行了表征。单晶结构解析表明,化合物1和2都属于正交晶系,Pccn空间群(No.56),晶体结构是由[Mn(1,2-dap)2(H2O)]2+配合物阳离子和[Sn2Q6]4-二聚体通过Mn-Q键连接而成的[Mn(1,2-dap)2(H2O)]2(μ-Sn2Q6)低聚体,相邻的低聚体之间通过氢键相连形成三维结构。化合物3属于三斜晶系,晶体结构是由[Mn(tren)]2(μ-Sn2S6)单元通过氢键连接而成的二维结构。紫外-可见漫反射光谱结果显示化合物1,2和3的带隙分别为2.5,2.1,2.4 e V,属于半导体材料。
Three multi-chalcogenides [Mn (1,2-dap) 2 (H2O)] 2 (μ-Sn2Q6) were synthesized by the solvothermal method with Q = S (1) and Se )] 2 (μ-Sn2S6) (3) The structure of the compound was characterized by X-ray single crystal diffraction and characterized by IR and UV-Vis diffuse reflectance spectroscopy. Single crystal structure analysis showed that both compounds 1 and 2 belong to orthorhombic, Pccn space group (No.56). The crystal structure is composed of [Mn (1,2-dap) 2 (H2O)] 2+ complex cation and The [Mn (1,2-dap) 2 (H2O)] 2 (μ-Sn2Q6) oligomer with [Sn2Q6] 4-dimers connected by Mn- Hydrogen bonds are connected to form a three-dimensional structure. Compound 3 belongs to the triclinic system. The crystal structure is a two-dimensional structure composed of [Mn (tren)] 2 (μ-Sn2S6) units connected by hydrogen bonding. The UV-Vis diffuse reflectance spectra showed that the bandgaps of compounds 1, 2 and 3 were 2.5, 2.1 and 2.4 e V, respectively, belonging to the semiconductor materials.
