Abstract
Abstract The [Co(acac) 2 ( N -phenylethylenediamine)] + (acac= 2,4-pentanedionate ion)and[Co(acac) 2 ( N,N′ -diphenylethylenediamine)] + complexes were separated into two and three racemic pairs of the diastereomers, respectively, by means of column chromatography and the diastereomers were resolved by the chemical method. The diastereomers are stable in acidic water pH (2.5), but easily epimerize in neutral or basic water. The isomer distributions at equilibrium were determined and the results compared with those of the corresponding N -methyl-substituted ethylenediamine complexes.
