n-octylated derivative (C8OL) were prepared in short sequences and good yields. The monocarbonyldichlororuthenium(II) complex (C8OL)Ru(CO)Cl2 were obtained in cis and trans isomeric forms, which could be distinguished by their absorption, 13C NMR and 15N NMR spectra. The octahedral homoleptic complexes [(C8OL)2M]2+ (M = RuII, FeII) and five-coordinate (HOL)NiCl2 are also described. Density functional theory
摘要制备了水溶性,羟苯基取代的二吡嗪基吡啶(HOL)及其脂溶性正辛基衍生物(C8OL),并以短序列和良好收率制备。以顺式和反式异构体形式获得单羰基二氯钌(II)络合物(C8OL)Ru(CO)Cl2,其特征在于它们的吸收,13C NMR和15N NMR光谱。还描述了八面体均质络合物[(C8OL)2M] 2+(M = RuII,FeII)和五坐标(HOL)NiCl2。密度泛函理论用于推导光学几何形状,光谱,分子轨道描述和电子结构。随时间变化的计算表明,造成均相FeII和RuII物质颜色强烈的可见区吸收主要来自内部配体电荷转移过程,而仅部分来自预期的金属到配体CT过程。还获得了游离C8OL,反式-(C8OL)Ru(CO)Cl2,[(C8OL)2Fe](FeCl4)2和(HOL)NiCl2的晶体结构。还介绍和讨论了电化学数据。
