Cobalt(III) complexes containing a tripodlike quadridentate ligand, tris(2-aminoethyl)amine or nitrilotriacetate, and a chiral bidentate, L-amino carboxylate or (R)-propylenediamine, are prepared and separated into their respective geometricalisomers. The two geometricalisomers have mutually quasi-enantiomeric configurations. Circular dichroism spectra in the d-d absorption band region are discussed

Abstract The main emphasis in the study has been the investigation of the kinetics of the stepwise reactions of [Co(tren)C2O4]+ ion [tren = 2,2’,2”-triaminotriethylamine, N(CH2CH2NH2)3] in both dilute and concentrated acids, as well as the characterization in solution of some new Co(III) tren complexes. The aquation reaction was conducted in 1.0 M HClO4 solution under various conditions. Protonation
