| 摘要: 用水热法合成了一个新的镉配位聚合物[Cd(BIMB)0.5(glu)]n(BIMB=1,4-二(咪唑基)苯,H2glu=戊二酸),用红外,元素分析进行了表征。X射线单晶衍射分析表明配位聚合物属于单斜晶系,P21/c空间群,a=0.822 06(5) nm,b=0.774 38(5) nm,c=1.877 93(10) nm,β=107.966°,V=1.137 nm3,Z=4,F(000)=684。在配合物中,相邻的镉原子通过2个戊二酸连接成一维链状结构,链状结构通过另一戊二酸拓展成二维层状结构,相邻二维层状结构进一步由BIMB配体拓展成三维骨架结构。热重分析表明配合物具有较好的稳定性,荧光光谱分析表明配合物具有较好的荧光性质。 |

| Abstract: A new complex [Cd(BIMB)0.5(glu)]n based on rigid ligand BIMB (BIMB=1,4-bis(imidazol-1-yl)benzene) and flexible ligand H2glu (H2glu=glutaric acid) has been synthesized by hydrothermal method and characterized by IR and elemental analysis. The complex crystallizes in the monoclinic system P21/c space group, a=0.822 06(5) nm,b=0.774 38(5) nm, c=1.877 93(10) nm, β=107.966°,V=1.137 nm3, Z=4, F(000)=684. In complex, the adjacent Cd(Ⅱ) atoms are connected by two glu2-ligands to result in 1D chains, which are further linked by another glu2-ligand to generate a 2D layers, and the adjacent 2D layers are linked by BIMB ligand to result in a 3D framework. The TGA analysis shows the complex has good thermal stability. The fluorescence analysis reveals the complex has good fluorescence property. CCDC: 891527. |
