| 摘 要： | 水热条件下合成了具有超大孔道和层状结构的有机模板稀土硫酸盐。超大孔道的稀土硫酸盐（1）的分子式为（CH3）2NH2]9Pr5（SO4）12]·2H2O，它展现出有趣的交叉二十元环孔道结构。层状的稀土硫酸盐的分子式为H3O]3（CH3）2NH2]3Ln2（SO4）6]（Ln=Pr，2；Nd，3），它可以被看作是由双链和八元环结合而成。这3种化合物的合成揭示了大的有机胺（三聚氰胺）可能用作为第二结构导向剂，阻止形成高维数的无机骨架，从而诱导了二维层状结构稀土硫酸盐晶体的生长。对化合物1和3的磁性进行了研究，测试的温度范围在2~300 K。

| 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]9Pr5(SO4)12]·2H2O (1), exhibit an interestingly intersecting 20-membered ring channels. The layered lanthanide sulfates, formulated asH3O]3(CH3)2NH2]3Ln2(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. CCDC:1553358, 1; 1553359, 2; 1553360, 3. |
