The Pfeiffer effect is studied in a series of thirteen coordination compounds of cobalt (III) of type [Co(AA)3]n+ and [Co(AA)2 BB]n+ where AA and BB are 1,10-phenanthroline, 2,2'-bipyridyl, oxalate or corbonate ions, cis-[Co(bpy)2X2]+ (X = Cl or NO2-) and cis-[Co(phen)2Cl]+ ions in presence of (+)-cinchonine hydrochloride and (+)-tartaric acid. Two new chiral environment compounds i.e. (+)-ascorbic acid and (-)-lysine also induce this effect in a few complexes. The effect is used to correlate the absolute configurations of these complexes with that of standard compounds like A-K3[Co(ox)3].
