Abstract
Seven new optically active complexes of fac-Δ- and fac-Λ-[Co2(L-armoH)3(L-amo)3]3+ type have been prepared, where L-amoH and L-amo denote L-aminoalcohol and L-aminoalcoholate ion, respectively. The geometrical and the absolute configuration around the metal ion of these complexes have been determined on the basis of their absorption and circular dichroism (CD) spectra. The complexes are monomeric tervalent complex ions in acid solution. In organic solvents and in crystalline states, they seem to have a dimeric structure with face-to-face O···H···O hydrogen bonds between three OH groups of the triprotonated [Co(L-amoH)3]3+ and three oxygen atoms of the deprotonated [Go(L-amo)3]0.Keywords
