Preparation and Characterization of [Co2(bidentate-N,S)3(triamine)]-Type S-Bridged Dinuclear Complexes

Abstract
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.
