本文用氯化钴、间苯二甲酸钠、1-乙基咪唑在乙醇和水的混合溶剂中反应得到了配位聚合物[Co(ip)(Eim)2]n(其中ip2-为间苯二甲酸二价阴离子,Eim为1-乙基咪唑),用X单晶衍射方法测定了其晶体结构。晶体属单斜晶系,P21/c空间群。配合物结构中含有沿着b轴延伸的“zigzag”链,每个Cu原子分别与2个N原子、2个O原子进行配位,形成了一个扭曲的四面体结构。热重分析表明配合物的分解经历了3个阶段。电化学研究显示配合物中的Co2+/Co3+氧化还原是一个准可逆的过程。
In this paper, cobalt (Ⅱ), sodium isophthalate and 1-ethylimidazole were used to react with a mixed solvent of ethanol and water to obtain a coordination polymer [Co (ip) (Eim) 2] n Formic acid dianion, Eim is 1-ethylimidazole), its crystal structure was determined by X-ray single crystal diffraction. Crystal is monoclinic, P21 / c space group. The complex structure contains “zigzag ” chains extending along the b axis. Each Cu atom coordinates with two N atoms and two O atoms respectively to form a twisted tetrahedral structure. Thermogravimetric analysis shows that the decomposition of the complex has gone through three stages. Electrochemical studies show that the Co2 + / Co3 + redox complex is a quasi-reversible process.
