摘　　要：以Sm(NO3)3.6H2O和丁二酸为原料,采用水热合成法合成了1种新型三维微孔稀土金属配位聚合物{Sm2(C12H12O12)3(H2O)2}n.通过元素分析确定标题化合物的元素值,同时用热重表征标题配合物,晶体结构经X射线单晶衍射仪分析确定,标题配合物的晶系为三斜晶系,P-1空间群,晶胞学数据:a=0.776 24(15)nm,b=0.808 53(10)nm,c=1.416 00(3)nm,α=96.901 0(3)°,β=97.020 0(3)°,γ=103.364(3)°,V=0.848(3)nm3,Z=2,F(000)=640,R1=0.053 0[I>2σ(I)],wR2=0.142 7.The title compound of {Sm2（C12H12O12）3（HO2）2}n was synthesized by the hydrothennal reaction of Sm（NO3）3. 6H2O and succinic acid with 1 ： 1 mole ratio. The structure of the compound was revealed by single-crystal X-ray diffraction analysis. Element value of the title complex have been characterized by elemental analysis and the title compound have been characterized by thermogravimetry. It was assigned to triclinic crystal system, space group P-1. For the title compound： a=0.77624（15）nm,b=0.80853（10）nm,c=1.41600（3）nm,α=96.9010（3）°,β=97.0200（3）°,γ=103.364（3）°,V=0.848（3）nm^3,Z=2,F（000）=640,R1=0.0530 and wR2=0. 142 7 for 2737 observed reflections with I〉2σ（I）.
