摘要: 水热法合成得到2个配合物,{[Zn7(L)4(bpe)2(μ3-OH)2(H2O)8]·4H2O}n(1),和{[Cd3(L)2(bpy)2.5(H2O)]·5.5H2O}n(2)(H3L=3-(carboxymethoxy)benzene-1,2-dioic acid, bpe=1,2-bis(4-pyridyl)-ethene, bpy=4,4'-bipyridine),并采用元素分析、红外光谱、热重和X-射线单晶衍射对其结构进行表征。配合物1中,配体L3-和bpe连接[Zn5(μ3-OH)2]中心形成一维链,这样的链通过氢键连接成三维的超分子结构。配合物2呈现(3,3,6)连接的网状结构。此外,对配合物1和2的荧光性质进行了研究。 |

Abstract: Two coordination polymers, {[Zn7(L)4(bpe)2(μ3-OH)2(H2O)8]·4H2O}n (1), and {[Cd3(L)2(bpy)2.5(H2O)]·5.5H2O}n (2) (H3L=3-(carboxymethoxy)benzene-1,2-dioic acid, bpe=1,2-bis(4-pyridyl)-ethene, and bpy=4,4'-bipyridine), have been synthesized under hydrothermal condition. Both complexes were characterized by elemental analysis, IR spectra, thermogravimetric analysis (TGA), and single-crystal X-ray crystallography. Complex 1 features a three-dimensional supramolecular architecture linked through hydrogen bonding interactions in which the secondary building unit (SBU) is [Zn5(μ3-OH)2] cluster. Complex 2 features three-dimensional metal-organic framework with (3,3,6)-connected topology. The luminescence behaviors of 1 and 2 were also discussed. CCDC: 965303, 1; 965304, 2. |
