| Abstract: Extra-large-pore and layered organically templated lanthanide sulfates have been prepared under solvothermal conditions. The extra-large-pore lanthanide sulfates, with the composition [(CH3)2NH2]9[Pr5(SO4)12]·2H2O (1), exhibit an interestingly intersecting 20-membered ring channels. The layered lanthanide sulfates, formulated as [H3O]3[(CH3)2NH2]3[Ln2(SO4)6] (Ln=Pr for 2, Nd for 3), can be considered as combination of double-stranded chains and 8-membered rings. The synthesis of three compounds demonstrates that large organic amine (1,3,5-triazine-2,4,6-triamine) may be used as the second structural directing agent to prevent the formation of high dimensional inorganic framework as well as inducing crystal the growth of 2D layer structural lanthanide sulfates. The magnetic property of compounds 1 and 3 has been investigated through the magnetic measurement over the temperature range of 2~300 K. |
