摘　　要：以4,4-二(4-羟乙基苯并咪唑基苯基)丙烷(L1),4,4-二(4-羟乙基咪唑基苯基)丙烷(L2)为原料,通过水热法得到2个二维结构的配位聚合物{[Cd(L1)(bdc)H2O]·2DMA}n(1),[Cd(L2)(bdc)H2O]n(2)(H2bdc=对苯二甲酸,DMA=N,N-二甲基乙酰胺),通过X-射线单晶洐射、热重以及红外光谱对其进行了表征。结果显示晶体1为单斜晶系,P2/c空间群。晶体2为单斜晶系,C2/c空间群。配合物2为2D→2D穿插结构。热重分析表明配合物1和2分别在343和325℃时分解。Two 2D coordination polymers {[Cd（L1）（bdc）H2O]·2DMA}n, [Cd（L2）（bdc）H2O]n（H2bdc=terephthalic acid,DMA=N,N-Dimethylacetamide） based on 4,4-bis（4-hydroxyethyl benzimidazolyl phenyl）propane（L1）, 4,4-bis（4-hydroxyethyimidazolyl phenyl）propane（L2） have been synthesized under hydrothermal and structurally characterized by single crystal X-ray diffraction, IR spectroscopy, thermogravimetry and powder X-ray diffraction（PXRD）. The results shows that compound 1 crystallizes in the monoclinic system, space group P2/c. Compound 2crystallizes in the Monoclinic system, space group C2/c. Compound 2 was 2D →2D interpenetrated frameworks.The TG analysis shows that the complexes 1 and 2 were decomposed at 343 and 325 ℃, respectively. CCDC：990975, 1; 990976, 2.
