| 中文摘要: |
| 本文通过水热合成的方法制备得到了一个新型的二维金属有机配位聚合物[Co2(L1)(4,4’-bipy)(3H2O).2H2O]n (1), (H4L1 = 3,3'-(1,4-苯二氧基)二邻苯二甲酸; 4,4’-bipy = 4,4’-联吡啶)，并对其结构进行了系统的表征。研究表明3,3'-(1,4-苯二氧基)二邻苯二甲酸配体中的羧酸采用μ1-η1-η0和μ1-η1-η1两种桥联的方式跟两个钴离子配位形成十四圆环，形成的十四圆环被3,3'-(1,4-苯二氧基)二邻苯二甲酸配体连接进一步形成之字形的一维链状结构。最终，辅助配体4,4’-联吡啶将这些一维链状结构连接起来形成二维的(44)-sql网状拓扑结构。在本文中，我们还一步研究了这个配位聚合物的红外光谱以及热稳定性。 |
| 英文摘要: |
| A 2D metal organic coordination polymer of Co(II), [Co2(L1)(4,4’-bipy)(3H2O).2H2O]n (1), (H4L1 = 3,3'-(1,4-phenylenebis(oxy))diphthalic acid; 4,4’-bipy = 4,4’-bipyridine) composed of mixed ligands system has been synthesized and structurally characterized. The carboxylate group in L1 adopts μ1-η1-η0 and μ1-η1-η1 bridging modes to link two Co(II) ions to form a 14-membered-ring, and then the 14-membered-ring connects each other to furnish a zig-zag chain by L1 ligand. Finally, the linear 4,4′-bipy ligand links these chains in a vertical direction resulting in a typical 2D (44)-sql topological net. In addition, IR spectrum and thermal stability were also investigated systematically. |
