【摘要】 合成了三维超分子化合物[Cu(tzda)(phen)(H2O)]n(H2tzda为1,3,4-噻二唑-2,5-二硫代乙酸,phen为邻菲咯啉),测定了其晶体结构.结果表明:配合物属单斜晶系,空间群P21/c.配合物中,与金属中心Cu(Ⅱ)离子配位的3个氧原子分别来自2个tzda2-配体酸根和1个水分子,2个氮原子则来自同一个1,10-邻菲咯啉分子,形成五配位的变形四角锥结构.由于tzda2-的桥联作用以及氢键和π-π弱堆积作用,配合物堆积成三维超分子网状结构.对配合物的电化学研究表明:在–0.6 V～+0.4 V电位范围内,Cu2+/Cu+电对在电极上的氧化还原反应过程是准可逆过程且受扩散控制.更多还原

【Abstract】 A new 3D supramolecular compound,[Cu(tzda)(phen)(H2O) ]n[H2tzda =(1,3,4-thiadiazole-2,5diyldithio) diacetic acid,phen = phenanthroline],were synthesized and characterized.It crystallized in monoclinic space group P21/ c.The Cu(Ⅱ) ion exhibited a distorted quadrangular pyramid geometry,involving three oxygen atoms of two tzda2-anions and one water molecule,and two nitrogen atoms of one 1,10-phenanthroline.The complex molecules formed 3D supramolecular network structure by bridging of tzda2-,hydrogen bond and π-π weak stacking interactions.Electrochemical study on the complex showed that the redox process(Cu2 + / Cu+) in the potential range of-0.6 V to + 0.4 V is quasi-reversible and controlled by the diffusion.更多还原
