Abstract The preparations of a series of optically active complexes with the general formula Co(NH2)5(OCOCH(X)CH3)2+ are reported for X = NH3 +, OH, F, Cl, Br, C2H5, and C6H5. The circular dichroism spectra of the complexes have been measured in aqueous solution, in the presence of salts of polarizable anions, and in KBr disks. The spectra have been analysed in terms of three Cotton effects under the 1A1g → 1T1g cubic absorption band and found to be consistent with a +, -, - sign pattern for the L-isomer, corresponding to the two components of the 1A1g → 1Eg (D4h) and to the 1A1g → A2g(D4h) transition, respectively.
