A new complex of copper(II) picrate (pic) with 1, 3-bis(1-allaylbenzimidazol-2-yl)-2-oxopropane (aobb), with the composition [Cu(aobb)2](pic)2, was synthesized and characterized. The crystal structure of the copper(II) complex revealed that the coordination environment around the central copper(II) atom is a distorted octahedral arrangement.

苦味酸铜 (II) (pic) 与 1, 3-双(1-烯丙基苯并咪唑-2-基)-2-氧代丙烷 (aobb) 的新配合物,其组成为 [Cu(aobb)2](pic)2,被合成和表征。铜(II)配合物的晶体结构表明,中心铜(II)原子周围的配位环境是扭曲的八面体排列。电子吸收光谱、溴化乙锭置换实验和粘度测量表明,配体和 CuII 复合物可以与小牛胸腺 DNA 强结合,大概是通过嵌入机制。此外,CuII配合物的抗氧化活性通过体外超氧化物和羟基自由基清除方法测定,表明CuII配合物具有抑制OH·和O2·-的活性。
