| 摘要: 用水热法合成了3个配位聚合物并测定了其晶体结构,分子式分别为[Zn2(tba)2(bpy)]n(1),[Zn2(tba)2(bpe)]n(2)和[Zn(tba)(bpp)]n(3),(tba=2,2'-thiobis(benzoic acid),bpy=4,4'-bipyridine,bpe=1,2-bis(4-pyridyl)ethylene,bpp=1,3-bis(4-pyridyl)propane)。tba是由2-(2-cyanophenylthio)benzoicacid原位水解得到的。X射线单晶衍射分析表明配合物1含双核锌单元,由tba和bpy连成二维(4,4)网。配合物2是基于[Zn2(tba)2]n子链,由bpe连接而成的钻石拓扑三维结构。有趣的是,配合物3是一个由(4,4)网交缠形成的二维到二维的聚索烃。Tba配体构型和各双吡啶辅助配体引起了3个化合物的结构各异性。此外,研究了3个配位聚合物的荧光性质。 |

| Abstract: Three complexes, namely [Zn2(tba)2(bpy)]n(1), [Zn2(tba)2(bpe)]n(2) and [Zn(tba)(bpp)]n(3), (tba=2,2'-thiobis(benzoic acid), bpy=4,4'-bipyridine, bpe=1,2-bis(4-pyridyl)ethylene, bpp=1,3-bis(4-pyridyl)propane) have been synthesized by methods of hydrothermal reaction and their crystal structures were determined. The ligand tba was generated via in situ hydrolyzation of 2-(2-cyanophenylthio)benzoic acid. Complex 1 has dinuclear Zn(Ⅱ) units, which are linked by tba and bpy to generate a two-dimensional (4,4) net. Complex 2 has a three-dimensional structure based on [Zn2(tba)2]n sub-chains, which are further connected by the bpe ligands to form a diamond topological network. Complex 3 possesses interesting2D→2Dpolycatenation of (4,4) networks. The structure versatility indicates that the coordination vector of tba and auxiliary bipyridine ligands play a crucial role in modulating the dinuclear zinc coordination polymers of 1~3. The photoluminescence properties of 1~3 in the solid state are also investigated. |
