| 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。 |

| Abstract: 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 2 crystallizes 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. |
