5-(3-吡啶基)间苯二甲酸构筑的镉(Ⅱ)配位聚合物的合成、晶体结构及荧光性质(英文)

Synthesis,Crystal Structure and Luminescence Property of a Cd(Ⅱ) Coordination Polymer Constructed by 5-(Pyridin-3-yl)isophthalic Acid

由5-(3-吡啶基)间苯二甲酸(H2pyip)为配体合成了一个Cd配位聚合物[Cd(pyip)(H2O)2]n(1)(H2pyip=5-(3-吡啶基)间苯二甲酸),并对其进行了元素分析、IR,热分析以及X射线单晶衍射法表征。晶体结构表明:配合物1属于六方晶系,P61空间群,配合物1中心镉原子是略微变形的八面体构型,该化合物通过5-(3-吡啶基)间苯二甲酸连接成了三维网格结构。配合物1的荧光测试表明它具有绿色荧光。

A cadmium coordination polymer [Cd（pyip）（H2O）2]n （1） was obtained by hydrothermal assembly of cadmium acetate dihydrate with 5-（pyridin-3-yl）isophthalic acid （H2pyip）. Complex 1 crystallizes in hexagonal space group P61 with a=b=1.052 66（3）, c=2.044 42（10） nm, T=120.00°, V=1.961 90（12） nm^3, Z=6, R1=0.022 5, wR2=0.046 7. Single crystal diffraction revealed that each Cd center located in a slightly distorted coordination environment and it is further connected by pyip to give a three dimensional network structure. In addition, the element analysis, IR, TG and luminescent properties of polymer 1 have been investigated at room temperature. CCDC： 854164.
