摘要
利用四氮唑-1-乙酸(Htza)和1,10-邻菲罗啉(phen)混合配体与三氟甲基磺酸铜(Cu(CF3SO3)2)在常温条件下反应得到1个单核Cu(Ⅱ)配合物[Cu(tza)(phen)2]2·(CF3SO3)2·0.5H2O(简称配合物1).通过元素分析、红外光谱、单晶X-射线衍射和粉末X-射线衍射对其组成和结构进行了表征.单晶X-射线衍射分析结果表明,配合物1是通过单核阳离子[Cu(tza)(phen)2]2+和CF3SO3-阴离子之间的静电引力,1,10-邻菲罗啉芳香环之间的π-π堆积作用,以及四氮唑杂环与晶格水之间的OH幆N弱氢键作用形成的稳定的三维超分子结构.对配合物1的电化学性质进行了初步研究,并利用量子化学计算对配合物1金属离子的六配位畸变八面体构型进行了理论研究.
A new mononuclear copper ( Ⅱ ) complex [ Cu (tza)(phen)2]2.(CF3SO3)2. ( 0. 5H2O ( 1 ) was synthesized by the reactions of tetrazole-1-acetic acid (Htza) and 1, 10-phenan- throline (phen) with Cu (CF3SO3)2 at room temperature. The composition and structure of 1 were characterized by elemental analysis, infrared spectroscopy, single-crystal X-ray diffraction and pow- der X-ray diffraction. The result of single-crystal X-ray diffraction analysis reveals that the electro- static attractions between the [ Cu(tza) (phen) 2 ] 2 + cations and CF3SO3 anions, hydrogen bonding interactions between tetrazole rings of tza- ligands and lattie water molecules, as well as π -π aro- matic stacking interactions between the adjacent phen molecules result in a 3D supramoleeular struc- ture of 1. In addition, the electrochemical property of 1 was investigated, and the distorted oetahe- dral configuration of Cu ( Ⅱ ) was also studied by quantum chemistry calculation.
