Polarographic reduction behaviors of <I>fac</I>-[Cr(AA)<SUB>3</SUB>] complexes, where AA is an L-α-amino acidato ligand, have been studied in Me<SUB>2</SUB>SO. These complexes showed two reduction waves at mercury electrode and the first corresponded to Cr(III) → Cr(II). This reduction potential was found to be more positive for the (+)<SUB>546</SUB>-isomer than for the corresponding (−)<SUB>546</SUB>-isomer in the presence of Et<SUB>4</SUB>N<SUP>+</SUP>.
