The sym-fac-[Co(medien)(S)-Asp]ClO4 (medien = 4-methyl-1,4,7-triazaheptane) isomer was prepared from [Co(medien)Cl3] and Ag2(S)-Asp in the presence of charcoal. Since sym-fac isomer does not isomerize when equilibrated with charcoal, its formation is

Of the 12 possible diastereoisomers only Δ-cis(N)-trans(O5)-(RR)-Na[Co(alamp)2] isomer was isolated. Possible reasons explaining stereospecific coordination of ligand are discussed in terms of steric intra- and interligand interactions arising from
