一个基于原位转化三角有机配体/Zn的金属-有机配合物的合成、结构及荧光性质

A metal-organic complex based triangular ligand transformation in situ and Zn(Ⅱ):synthesis,structure and photoluminescence property

利用水热合成的方法,将有机配体3,5-di-[1,2,4]triazol-1-yl-benzonitrile(简称DTCN),原位转化生成3,5-di-[1,2,4]triazol-1-yl-benzoic acid(简称HDTBA)的同时,得到了一个基于金属Zn(II)的金属-有机配合物,[Zn(DTBA)Cl](1),并且借助X-射线单晶衍射(X-ray)、红外光谱等手段,对化合物1的结构进行了初步的表征.化合物1展示了一个2D的框架结构.两个中心金属Zn(II)原子桥连两个DTBA配体,形成了双核的环状结构单元{Zn/DTBA}2.这些结构单元彼此之间,以垂直的方式,通过Zn-N共价键作用,连接成为一个(4,4)-连接的2D网状结构.同时,我们还研究了这个配合物的荧光性质.

A metal - organic complex based on 3,5 - di - [ 1,2,4 ] triazol - 1 - yl - benzoic acid （HDTBA） and Zn （II）, [ Zn （DTBA）Cl ] （1）, has been synthesized under hydrothermal condition, which is characterized by single crystal X -ray diffraction and IR spectra. The ligand DTBA is prepared by the transformation in situ of 3,5 - di - [ 1,2,4 ] triazol - 1 - yl - benzonitrile （DTCN）. Compound 1 has a 2D layer structure, in which two DTBA are bridged through two Zn（II） atoms to give a binuclear circle building unit { Zn/DTBA}2. These building units { Zn/DTBA }2are linked each other in a perpendicular mode to form a 2D （4,4） - connected network. The photoluminescence property of compound 1 has also been studied.
