Three kinds of S-bridged dinuclear complexes, Δ- and Λ-[Co2(aet)3(dien)]3+ (aet=2-aminoethanethiolate and dien=diethylenetriamine), Δ- and Λ-[Co2(aet)3(dpt)]3+ (dpt=bis(3-aminopropyl)amine)), and ΔLLL-[Co2(l-cys-N,S)3(dien)] (l-cys=l-cysteinate), were prepared by the reactions of [Co(aet)3] or ΔLLL-[Co(l-cys-N,S)3]3− with [CoCl3(dien)] or [CoCl3(dpt)]. The isomers were characterized from their absorption, CD, and 13C NMR spectra.

氨基
乙硫醇和dien=
二乙烯三胺),Δ-和Λ-[Co2(aet)3( dpt)]3+ (dpt=双(3-
氨基丙基)胺))和ΔLLL-[Co2(l-cys-N,S)3(dien)] (l-cys=l-半胱
氨酸),通过以下方法制备[Co(aet)3] 或 ΔLLL-[Co(l-cys-N,S)3]3− 与 [CoCl3(dien)] 或 [CoCl3(dpt)] 的反应。通过吸收光谱、CD 光谱和 13C NMR 光谱对异构体进行了表征。
