摘要
通过溶剂热方法,用4′-对甲氧基苯基三联吡啶(meophtpy)与NiSO4.7H2O、NaClO4反应,合成了标题配合物[Ni(meophtpy)2].(ClO4)2,并通过红外光谱、紫外可见吸收光谱、X射线单晶衍射对配合物进行了结构表征。该配合物属单斜晶系,P21/c空间群,镍原子与2个4′-对甲氧基苯基三联吡啶的6个氮原子配位,形成六配位的八面体结构。该配合物的紫外可见吸收光谱在235.5、278.5、342 nm显示了三联吡啶的特征吸收峰,在396 nm显示了三联吡啶的特征荧光发射峰。根据循环伏安法分析其电化学性质,该配合物在-0.82 V有一个Ni2+的标准还原峰。
The title complex has been synthesized with 4＇-（p-methoxylphenyl）-2,2＇：6＇,2″-terpyridine （meophtpy） and zinc sulfate heptahydrate （NiSO4·7H2O）, sodium perchlorate （NaClO4） with solvothermal method and characterized by IR, UV and X-ray diffraction. It crystallizes in monoclinic space group P21/c. The crystal structure shows that the nickel atom is coordinated with six nitrogen atoms from two terpyridine molecules, forming six-coordinated octahedral coordination geometry. There are three abosrpsion peaks 235.5, 278.5 and 342 nm which are the typical absorption spectrum of terpyridine complexes. The fluerescence are peaked at 396 nm. Following a cyclic voltammetry measurement a typical reduction peak of Ni2＋ at -0.82 V was found. CCDC： 899537.
