Synthesis, Crystal Structure and Properties of a 2D Coordination Polymer: [Cd(C_4O_4)(C_(12)N_2H_8)(H_2O)]_n

本文采用邻菲罗啉和方酸为配体,在水热条件下通过自组装合成了具有二维网状结构的配位聚合物[Cd(C4O4)(C12N2H8)(H2O)]n,并应用X-光衍射技术测定了其单晶结构。结果表明:Cd原子与2个邻菲罗啉氮原子、3个方酸氧和1个水分子配位,生成了六配位扭曲八面体。方酸以少见的μ-1,2,3配位模式桥联3个中心金属离子,并进一步组装成二维网状配位聚合物。对配位聚合物的光学性能及热稳定性做了进一步的研究,实验结果表明:配位聚合物是具有良好热稳定性的强荧光材料,具有潜在的应用前景。

The 2D network coordination polymer of Cd ^Ⅱ with 1,10-phen and squaric acid, [Cd（C4O4）（C12N2Hs）（H2O）]n, has been synthesized by the hydrothermal method through self-assembling, and it＇s molecular structure has been characterized by X-ray single-crystal structure analysis. The results show that Cd （Ⅱ） is in six-coordinated distortered octahedron environment containing two Nphen, three Osquarate one Oaqua. The square bridging links three metal centers through a novel/x-1,2,3 coordination model, and which is further assembled into 2D network coordination polymer. The fluorescence at solid state and the thermal stability of the title complex have been coordination polymer presents a good fluorescent property and thermal stable property, and application prospects.
