| 摘要: 利用过渡金属镉（锌）盐与1，4-二（4-甲基咪唑）苯、间苯二甲酸分别采用分层和水热法合成了化合物{[Cd（BMIB）（H2O）2]（NO3）2}n（1）和{[Zn2（BMIB）1.5（OH）（IP）1.5]·H2O}n（2）（BMIB=1，4-二（4-甲基咪唑）苯，IP2-=间苯二甲酸根），并对其进行了元素分析、IR及X射线衍射法表征。晶体结构研究表明：配合物1属于三斜晶系，P1空间群。晶胞参数：a=0.382 08（3）nm，b=0.904 72（7）nm，c=1.378 29（10）nm，α=98.581（4）°，β=97.020（3）°，γ=94.398（3）°。配合物2属于单斜晶系，C2/c空间群。晶胞参数：a=3.764 07（9）nm，b=1.017 18（5）nm，c=2.015 31（11）nm，β=120.860（2）°。配合物1是由配体BMIB连接镉离子形成一维链状结构，由氢键连接成二维层结构。而配合物2是由配体IP2-连接锌离子形成一维梯状结构，该一维梯通过羟基和BMIB连接成三维网络结构。此外，配合物1和2具有较好的荧光性能。 |

| Abstract: The reaction of M(NO3)2·6H2O (M=Cd, Zn), isophthalic acid(H2IP) as well as 1,4-bis(4-methyl-imidazolyl)benzene(BMIB) results in formation of a 1D complex {[Cd(BMIB)(H2O)2](NO3)2}n (1) and 3D complex {[Zn2(BMIB)1.5(OH)(IP)1.5]·H2O}n (2). X-ray diffraction crystal structure analysis shows that 1 crystallizes in triclinic system, space group P1 with a=0.3820 8(3) nm, b=0.904 72(7) nm, c=1.378 29(10) nm, α=98.581(4)°, β=97.020(3)°, γ=94.398(3)°. In 1, BMIB links all the Cd atoms into a 1D chain, which forms 2D bilayer through the H-bond interactions. The complex 2 crystallizes in monoclinic system, space group C2/c with a=3.764 07(9) nm, b=1.017 18(5) nm, c=2.015 31(11) nm, β=120.860(2)°. On the other hand, in 2, the carboxylate group of ligand IP2- with μ2-η1:η1 coor-dination mode links metal atoms to give a 1D double-chain structure, which forms 3D network through Zn-N and Zn-OH interactions. In addition, the fluorescence property of complexes 1 and 2 have been investigated, which exhibit good fluorescence in the solid state at room temperature. CCDC:1511866, 1; 1511867, 2. |
