摘　　要：本文分别采用水热和溶剂热的方法,以乙二胺和哌嗪为有机模板剂分别合成了两种新的三维孔道结构的稀土硫酸盐[Gd2(SO4)5(H2O)2][C2N2H10]2(1),[Eu2(SO4)5(H2O)2][C4N2H12]2(2),并且通过单晶X射线衍射、元素分析、红外、热重对两种化合物进行了表征。化合物1和2都属于单斜晶系,P21/c空间群。化合物1:a=0.652 1(4)nm,b=1.692 0(9)nm,c=2.023 3(11)nm,β=95.168(7)°,Z=4。化合物2:a=1.972 1(2)nm,b=1.927 1(2)nm,c=1.323 20(14)nm,β=92.307 0(10)°,Z=8。单晶结构分析表明,这两种化合物的无机骨架都是由SO4连接具有交替十六元环与八元环二维层形成的三维孔道结构。化合物2的固体荧光分析表明,在396 nm的激发波长下表现出Eu3+的特有发光性质。Employing hydrothermal/solvothermal method and ethylenediamine or piperazine as organic template, two lanthanide sulfates [Gd2（SO4）5（H2O）2][C2N2H10]2 （1）, [Eu2（SO4）5（H2O）2][C4N2H12]2（2）, with three-dimensional channels have been synthesized and characterized by single-crystal XRD, ICP, IR and TGA. Both of the two compounds crystallize in the monoclinic space group P21/c. Crystal data for 1, a=0.652 1（4） nm, b=1.692 0（9） nm, c=2.023 3（11） nm, β=95.168（7）°, Z=4. For 2, a=1.972 1（2） nm, b=1.927 1（2） nm, c=1.3232 0（14） nm, β=92.307 0（10）°, Z=8. Crystal structure analysis reveals that both of the inorganic frameworks of compounds 1 and 2 have three-dimensional architectures which are formed by connecting of the two-dimensional layers possessing 8-membered rings and 16-membered rings with SO4. The solid state luminescent properties of compounds 2 were investigated and it displays a typical luminescent property of Eu3＋ with excitation wavelength at 396 nm. CCDC： 874219, 1; 874220, 2.
