| 摘要: 水热条件下,合成了2个结构新颖的金属配位聚合物:[Co1.5(btb)2(nbta)(H2O)2]n(1),[Cd(btb)0.5(nph)(H2O)]n(2)(btb=4,4'-二(1,2,4-三氮唑-1-基)联苯,H3nbta=5-硝基-1,2,3-苯三甲酸,H2nph=3-硝基邻苯二甲酸)并对它们进行了元素分析,红外光谱及X-射线单晶衍射等表征。结构分析表明,化合物1是一个二维(3,4)-连接3,4L90拓扑结构,并进一步通过O-H…O氢键作用构筑成三维超分子结构。而配合物2是一个三维(3,4,4)-连接的sqc69网络,它的拓扑符号为(4.82)2(42.82.102)(8.104.12)。此外,还研究了这两个配合物的热重和荧光性质。 |

| Abstract: Two metal-organic coordination polymers with novel structural based on a rigid bis(triazole) ligand, namely, [Co1.5(btb)2(nbta)(H2O)2]n (1), and [Cd(btb)0.5(nph)(H2O)]n (2) (btb=4,4'-bis(1,2,4-triazolyl-1-yl)-biphenyl, H3nbta=5-nitro-1,2,3-benzenetricarboxylic acid, H2nph=3-nitrophthalic acid) were synthesized hydrothermally and characterized by IR, elemental analysis, as well as single-crystal X-ray diffraction. Compound 1 features a 2D structure with a (3,4)-connected 3,4L90 topology, which ultimately is extended into a 3D supramolecular framework via O-H…O hydrogen bonding interactions. While complex 2 exhibits a 3D (3,4,4)-connected sqc69 network with the Schläfli symbol of (4.82)2(42.82.102)(8.104.12). Furthermore, the thermal stability and fluorescence properties of the complexes have been investigated. CCDC: 1055345, 1; 1063802, 2. |
