标题配合物是由三齿配体N,N-二(2-苯并咪唑甲基)亚胺(IDB)与NiSO4?6H2O在甲醇-乙醇溶液中反应得到的紫色晶体.X射线衍射测定了其单晶结构.结构分析表明,镍(II)分别与两个IDB配体中的苯并咪唑的四个氮和胺基的两个氮配位形成畸变的八面体构型.研究了纳米金和小牛胸腺DNA对配合物荧光的影响,探讨了配合物的荧光猝灭与恢复的可能机理.
The title complex is a purple crystal obtained by the reaction of tridentate ligand N, N-bis (2-benzimidazolylmethyl) imide (IDB) with NiSO4 · 6H2O in methanol-ethanol solution.The X-ray diffraction Single crystal structure.The structural analysis shows that nickel (II) complexes with the two nitrogen atoms of benzimidazole and the two nitrogen atoms of two IDB ligands respectively to form a distorted octahedral configuration.The effects of nano-gold and The effect of calf thymus DNA on the fluorescence of the complex was investigated and the possible mechanism of fluorescence quenching and recovery of the complex was discussed.
