• A series of new kinds of mixed cobalt(III) complexes, <I>trans</I> (O,X)-[Co(X) (aminoacidato) (diethylenetriamine)]Y, have been prepared and characterized by visible and ultraviolet, circular dichroism, and proton magnetic resonance spectroscopy for X=CN<SUP>−</SUP>, NO<SUB>2</SUB><SUP>−</SUP>, and Cl<SUP>−</SUP>; aminoacid=glycine, α-aminoisobutyric acid, L-alanine, L-valine, L-threonine, and L-proline; and Y=Br<SUP>−</SUP>, Cl<SUP>−</SUP>, or ClO<SUB>4</SUB><SUP>−</SUP>. The proton magnetic resonance spectra of the cyano mixed complexes show the existence of new conformational isomers, <I>endo</I> and <I>exo</I> forms, which concern the ligand CN<SUP>−</SUP> and the hydrogen atom attached to the central nitrogen atom of the meridionally coordinated diethylenetriamine ligand.
