A series of homoligated Ni(II) complexes formed from two phosphino thioether (P,S) chelating ligands has been synthesized and characterized. Interestingly, this included octahedral Ni(II) complexes which, unlike previously characterized d(8) Rh(I), Pt(II), and Pd(II) analogues, exhibit in situ exchange processes centered around chloride ligand dissociation. This was verified and studied through the
合成并表征了一系列由两个膦硫醚 (P,S) 螯合配体形成的 homoligated Ni(II) 配合物。有趣的是,这包括八面体 Ni(II) 配合物,与以前表征的 d(8) Rh(I)、Pt(II) 和 Pd(II) 类似物不同,它表现出以氯化物配体解离为中心的原位交换过程。通过从该系统中受控提取和引入氯离子来验证和研究这一点,这表明这些过程通过具有方形金字塔、四面体和方形平面几何形状的复合物进行。使用各种表征方法研究了这些配合物,包括单晶 X 射线衍射研究、溶液 (31)P(1)H} NMR 光谱、UV-vis 光谱和 DFT 计算。
