含氮、氧配体Zn(Ⅱ)配合物的合成及晶体结构
|
摘要
利用溶剂热法合成了一种新的配合物[Zn(2-NCP)(1,3,5-H_2BTC)(H_2O)]_2·4H_2O(1),其中2-HNCP和H_3BTC分别代表2-(1H-1,3,7,8-环戊二烯并[l]四氮杂菲-2-yl)-苯甲酸(2-HNCP)和1,3,5-苯三甲酸(1,3,5-H_3BTC).同时,利用元素分析、红外光谱(IR)、粉末X-射线衍射(XRPD)和X-射线单晶衍射等对晶体结构进行了表征.结果显示配合物为三维的超分子结构.
A new complex[Zn(2-NCP)(1,3,5-H_2 BTC)(H_2 O)]_2·4 H_2 O is synthesized by solvothermal method,in which 2-HNCP and H_3 BTC represent 2-(1 H-1,3,7,8-cyclopenta[1]tetraazaphen-2-yl)-benzoic acid(2-HNCP)and 1,3,5-benzenetricarboxylic acid(1,3,5-H_3 BTC)respectively.At the same time,the crystal structure is characterized by elemental analysis,infrared spectroscopy(IR),powder X-ray diffraction(XRPD)and X-ray single crystal diffraction.The results show that complex1 is a three-dimensional supramolecular structure.
