摘要/Abstract

摘要：

基于配体2,2'-联苯二羧酸(H₂oba),以水热法合成出双核簇状配位化合物[Zn₂(oba)₂·2H₂O]_n,并通过单晶X衍射分析、元素分析、荧光分析和热重分析对其进行结构表征。结果表明,配合物属于单斜晶系,P2₁/c空间群,配合物的晶胞单元中包含2个独立的锌离子、2个H₂oba配体和两个水分子。在配位键的作用下,配合物具有无限循环的一维链状结构,再通过氢键的作用最终形成二维空间结构。此外,还对该化合物做了抗氧化活性(SOD)的研究,抗氧化活性研究表明配合物有较好的抗氧化活性,其IC₅₀(半数抑制浓度)值为25.0 mg/L,是一种良好的超氧化物歧化酶(SOD)模拟物。
