Bischelates, three isomers of dicyanocobalt(III), <I>trans</I>-dichlorocobalt(III), and copper(II), and a monochelate, tetracyanoferrate(II), of the title diamine were prepared, and their CD spectra were reported. Major positive components were found for I<SUB>a</SUB> bands, as was to be expected for the preferred λ conformation, but minor positive components were observed for the I<SUB>b</SUB> band with the <I>trans</I>-dianionocobalt(III) complexes. The configurational and the vicinal effects, as calculated from the CD spectra of the <I>cis</I>-dicyanocobalt(III) complexes, are shown to be different from those of (1<I>R</I>,2<I>R</I>)-1,2-cyclohexanediamine. The CD spectra of the Fe(II) and Cu(II) complexes are consistent with the conformational effect of the title diamine.
