ResumoAbstract Triethylenetetramine (trien) cobalt(III) complexes with 1,2-ethanedithiolate (edt) or 1,2-ethanedisulfinate (edsi) were prepared and characterized by absorption, CD, and 13C NMR spectra. Each of the two complexes gave three possible geometrical isomers (cis-α, cis-β-RR,SS, and cis-β-RS,SR) which were separated and optically resolved by fractional crystallization and/or column chromatography.
