The ligand field absorption and circular dichroism (CD) spectra were examined not only for trans-difluoro bis(diamine)chromium(III) complexes with two identical chiral diamines but also for nine new mixed diamine complexes of the same type with different diamines, which were ethylenediamine, trimethylenediamine, (R)- and (S)-propylenediamine, (1R, 2R)-1,2-cyclohexanediamine, (2R, 4R)- and (2R, 4R)-2,4-pentanediamine. The additivity of the CD contributions from the individual chiral diamines were substantiated for most of these complexes. On this basis, the conformational and the vicinal CD contribution due to puckered diamine rings and asymmetric carbon atoms, respectively, were differentiated, and the CD origins of all the present complexes were discussed in connection with stereochemistry.
