| Two 3D Cd(Ⅱ) Coordination Polymers Based on Semi-rigid Dicarboxylic Acid Ligand | |
| 摘要: 通过引入2个不同的氮杂环配体，得到了2个Cd（Ⅱ）配位聚合物[Cd（m-phda）（btbb）0.5]n（1）和[Cd（m-phda）（hbmb）0.5]n（2）（m-H2phda=间苯二乙酸），并对它们的结构进行了表征。结构分析表明配合物1是一个6-连接的pcu拓扑网络，拓扑符号为412·63。配合物2是一个5-连接的sqp拓扑网络，拓扑符号为（44·66）。另外，配合物1和2表现出较好的热稳定性和不同的荧光行为。 | |

| Abstract: Two novel Cd(Ⅱ) coordination polymers(CPs), formulated as[Cd(m-phda)(btbb)0.5]n (1) and[Cd(m-phda)(hbmb)0.5]n (2) (m-H2phda=m-phenylenediacetic acid, btbb=1,4-bis(2-(4-thiazolyl)benzimidazole-1-ylmethyl)benzene, hbmb=1,1'-(1,6-hexane)bis-(2-methylbenzimidazole)) have been prepared by hydrothermal reactions of the semi-rigid ligand m-H2phda with Cd(Ⅱ) ions in the presence of two disparate N-heterocyclic co-ligands and further characterized by infrared spectra (IR), powder X-ray diffraction (PXRD), elemental analyses and thermogravimetric (TG) analyses. 1 possesses a 6-connected 2-fold interpenetrating 3D pcu topology net with point symbol of 412·63. 2 exhibits a 5-connected 3D sqp network with a Schläfli symbol of 44·66. Additionally, complexes 1 and 2 present better thermal stabilities, as well as 1 and 2 also show different photoluminescence behaviors in the solid state. | |
