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.
