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. |
