Structural and chemical studies defining the configurational isomers of the triethylenetetra-amineglycinatocobalt(III) ion, [Co(trien)(gly)]2+

Abstract

The configurations of Δ(–)₅₈₉-β₁-RR and Δ(–)₅₈₉-β-₁-RS[Co(trien)(gly)]²⁺, and of β₂-(RR,SS)[Co-(trien)(gly)]²⁺ in two conformational modifications, have been determined by X-ray techniques; the structures and the mutarotation and equilibrium studies allow all the β₁,β₂, and α configurations to be assigned, and the results are correlated with calculations on the structures of minimum energy and with a calorimetric study.
