Abstract
Fourteen complexes of the type [Co(aa)2phen]X and [Co(aa)2dipy]X (where aa is the anion of glycine, β-alanine, l-serine, or l-proline) were newly prepared. Two geometrical isomers (trans(N) and cis(O)cis(N)) for the glycinato and β-alaninato complexes, four geometrical and/or diastereomeric isomers ((+)d- and (−)d-trans(N) and -cis(O)cis(N)) for the l-serinato complexes, and two diastereomers ((+)d- and (−)d-trans(N)) for the l-prolinato complex were separated. These complexes were characterized by absorption, circular dichroism spectra, and 1H and 13C NMR spectra. The absolute configurations of the l-serinato and l-prolinato complexes were assigned as Λ and Δ for the (+)d- and (−)d- isomers, respectively.Keywords
