硫属化合物dienH2Hg2Sb2S6（dien = diethylenetriamine）的溶剂热合成及其晶体结构

摘要

在400K温度下，以HgCl2，Sb粉和S粉为原料，将其按化学计量比进行混合，在二乙烯三胺和水混合溶剂的条件下，通过溶剂热合成方法反应得到了一个新的硫属化合物[dienH2]Hg2Sb2S6.通过元素分析和X-射线单晶衍射仪对此化合物进行结构表征，该晶体属于正交晶系，空间群为Cmca.该化合物由二维层状的[Hg2Sb2S6]2-阴离子和质子化的[dienH2]2+阳离子组成，两种结构通过氢键相互连接形成二维层状结构.%A new transition metal complex directedmercury thioantimonate, [dienH2]Hg2Sb2S6(dien = diethylenetriamine), has been synthesized by solvothermal reaction of HgCl2, Sb and S in diethylenetriamine solution at 400 K. The crystal structure was characterized by elemental analysis and single-crystal X-ray diffraction. The title compound crystallizes in the orthorhombic system (Cmca). The structure consists of two-dimensional (2D) [Hg2Sb2S6]2 -layer and protonated diethylenetriamine cation[dienH2]2+. These two types of units are interlinked via various hydrogen-bonding interactions to from a two-dimensional (3D) framework.
