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。
Under hydrothermal conditions, two novel metal coordination polymers were synthesized: [Co1.5 (btb) 2 (nbta) (H2O) 2] n (1) )] n (2) (btb = 4,4’-bis (1,2,4-triazol- 1-yl) biphenyl, H3nbta = 5-nitro-1,2,3-benzenetricarboxylic acid, H2nph = 3-nitrophthalic acid) and their elemental analysis, infrared spectroscopy and X-ray single crystal diffraction characterization. Structural analysis shows that compound 1 is a two-dimensional (3,4) -connected 3,4L90 topology and further constructed into a three-dimensional supramolecular structure by O-H ... O hydrogen bonding. Complex 2 is a three-dimensional (3,4,4) -connected sqc69 network with a topological symbol of (4.82) 2 (42.82.102) (8.104.12). In addition, the thermogravimetry and fluorescence properties of these two complexes were also investigated.
