Several (diamine)(2,9-dimethyl-4,7-diazadecane-2,9-dithiolato)cobalt(III) complexes, [Co(SNNS)(diamine)]+ (diamine=1,2-ethanediamine and (R,R)-1,2-cyclohexanediamine), were prepared and characterized by the visible-UV absorption, circular dichroism(CD), and 13C NMR spectra. The above SNNS quadridentate ligand gave only the cis-β geometrical isomer, which was chromatographically separated into two diastereomers
几种(二胺)(2,9-二甲基-4,7-二氮杂癸烷-2,9-二硫醇合)钴(III)配合物,[Co(SNNS)(二胺)]+(二胺=1,2-乙二胺和(R ,R)-1,2-环己二胺),通过可见-紫外吸收、圆二色性 (CD) 和 13C NMR 光谱进行表征。上述SNNS四齿配体仅产生顺-β几何异构体,由于手性氮原子的构型,其被色谱分离为两种非对映异构体。所有硫代和相应的亚磺酸根配合物在 Co(σ*)←S(σ) 配体-金属电荷转移带区域中表现出两个相反符号的 CD 带。发现符号模式与这些复合体的绝对构型有关。
