| 摘要: 利用一种柔性二羧酸,辅以不同的双咪唑配体在水热条件下构筑了两例具有穿插特征的钴配位聚合物,{[Co(bimb)(L)]·H2O}n(1)和{[Co(bbix)(L)]2}n(2)(H2L=4,4'-(2,2'-oxybis(ethane-2,1-diyl)bis(oxy))dibenzoicacid,bimb=1,1'-(1,4-butanediyl)bis(imidazole),bbix=1,4-bis(benzimidazole-1-ylmethyl)-benzene)。单晶X-射线衍射研究发现配合物1为2D→3D 4-连sql拓扑构型的三重穿插网格;配合物2为3D 4-连66dia拓扑构型的六重穿插网格。该结构分析结果表明作为辅助配体的双咪唑配体的构型对配合物的穿插特征有重要影响。另外,我们还研究了配合物1和2的热稳定性及磁性。 |

| Abstract: Two interpenetrating networks, namely {[Co(bimb)(L)]·H2O}n(1) and {[Co(bbix)(L)]2}n(2) (H2L=4,4'-(2,2'-oxybis(ethane-2,1-diyl)bis(oxy))dibenzoic acid, bimb=1,1'-(1,4-butanediyl)bis(imidazole), bbix=1,4-bis(benzimidazole-1-ylmethyl)-benzene) have been prepared under hydrothermal condition by varying the bis(imidazole) coligands. Single crystal X-ray diffraction indicates that complex 1 displays 2D→3D 3-fold interpenetrating framework with 4-connected sql topology; 2 shows a 3D 4-connected framework of 66 dia topology with 6-fold interpenetration. The results indicate that the shapes of bis(imidazole) coligands have an important effect on the interpenetrating characters and ultimate frameworks. Moreover, the thermal and magnetic properties of the two complexes have also been studied. |
