摘要:
在水热条件下利用间苯二乙酸、4,4′-二吡啶丙烷和硝酸锌反应生成配合物[Cd(pda)(bpp)]n(1)(1,3-pda=间苯二乙酸、bpp=4,4′-二吡啶丙烷).采用红外光谱、差热-热重、C H N元素分析、荧光及单晶X-射线衍射等手段对晶体结构进行了表征.配合物属单斜晶系,空间群为 P21/n;晶体学参数:a =0.8534(9)nm,b=2.3754(3)nm,c=1.0628(1)nm;β=98.858(1)°,V=2.1322(4)nm3.从b轴来看,4,4′-二吡啶丙烷与Zn(II)离子交替连接形成1维Z字链,链与链之间再通过间苯二乙酸的支撑作用构成2维(4,4)网格面.同样的2个网格面进行反平行相互交错,这可能与4,4′-二吡啶丙烷的柔性有关.荧光性质研究表明:配合物1在366 nm处呈现较强的荧光发射(λex =300 nm).
Abstract:
The compound[Zn(pda)(bpp)]n(1)has been hydrothermally synthesized and characterrized by means of elemental analysis,IR,TG-DSC and fluorescence,single crystal X-ray diffraction. The results show that the com-pound is monoclinic,with space group P21/n,a=0. 853 4(9)nm,b=2. 375 4(3)nm,c=1. 062 8(1)nm;β=98. 858(1)°,V=2. 132 2(4)nm3 . Along the crystallographic b axis,the bpp ligands bridge the ZnII centers to form parallel zigzag chains,which are interconnected to each other through the 1,3-pda ligands to result in the infinite (4,4)layer. Two independent(4,4)layers are interpenetrating to each other in an anti-parallel fashion. The corru-gated nature of the layer may be attributed to the backbone flexibility of bpp. The photoluminescence properties of compound 1 was also investigated,and it shows intense photoluminescence properties at 352 nm(λex =300 nm).
