摘要: 通过溶剂热技术合成了一种以二亚乙基三胺(dien)为模板的链状结构硫酸钬(H3dien)[Ho(SO4)3(H2O)2] (1),并通过X射线分析、红外光谱、元素分析和粉末衍射进行了表征。X射线晶体结构分析,化合物1结晶于单斜晶系,P21/c空间群,a=0.660 20(13) nm,b=1.476 7(3) nm,c=1.655 6(3)nm,β=93.313(2)°,V=1.611 4(5) nm3,Z=4。化合物1是由HoO8多面体和SO4四面体为建筑单元构建成新颖的单一链状结构。在a轴方向上,配位水分子通过氢键连接相邻的链形成三维超分子结构。有机胺分子镶嵌于链间,在合成化合物1合成过程中,pH值(pH=1.5)起了关键作用。

Abstract: A diethylenetriamine templated holmium sulfate (H3dien)[Ho(SO4)3(H2O)2] (dien=diethylenetriamine) (1) with a single chain structure has been synthesized solvothermally and the structure has been characterized by single-crystal X-ray diffraction, IR, TGA, ICP and XRD. Single crystal X-ray diffraction illuminates that the compound 1 crystallizes in the monoclinic crystal system, space group P21/c with cell dimension: a=0.660 20(13) nm, b=1.476 7(3) nm, c=1.655 6(3) nm, β=93.313(2)°, V=1.611 4(5) nm3, Z=4. Crystal analysis of compound 1 shows a single chain constructed from HoO8 polyhedra and SO4 tetrahedra. Coordination water molecules link adjacent chains by using hydrogen bonds to generate 3D supermolecule structure assembly along a axis, whereas the organic amines are located between the chains. And also, during the formation of 1, the pH value (1.5) plays an important role. CCDC: 841765.
