AB  - Two diastereomers of bis(1,3-diaminopropane)(S-phenylalaninato)cobalt(III) were prepared by reaction of S-phenylalanine with carbonatobis(1,3-diaminopropane)cobalt(III). The diastereomers were separated on an optically active Sephadex QAE column and their absolute configurations assigned by means of circular dichroism. In addition, H-1 NMR spectra of the diastereomers were analyzed in terms of the population of the three predominant rotamers of the coordinated S-phenylalaninato ligand. One out of 24 theoretically possible diastereomers of the dinuclear species di-mu-hydroxo-tetrakis(S-phenylalaninato)dicobalt(III) was obtained by direct synthesis and its absolute configuration deduced from CD spectra.

AB  - Rotamer population of S-tyrosinato and S-phenylalaninato ligands side groups in diastereomers of (1,2-diaminoethane)bis(S-aminocarboxylato)cobalt(III) complexes is calculated by vicinal alpha and beta proton coupling constant analysis. The effect of noncovalent intra- and interligand interactions on the population of rotamers in D2O solution is discussed. It has been established that in all the complexes investigated the most abundant is rotamer t, in which aromatic voluminous moiety and carboxylic group are in an anti position. In almost all complexes the lowest content is of rotamer g, in which these two groups are in the nearest position. Relatively high population of rotamer b in complex 5 tyr, in spite of high steric hindrances, is due to intra- and interligand NH... pi interactions.

AB  - In the reaction of trans-[CoCl2(en)(2)](+) with L-tyrosine all six theoretically possible diastereomers of the (1,2-diaminoethane)bis(L-tyrosinato)cobalt(III) complex were formed. The following five were isolated: Delta -trans(O); and Lambda- and Delta -C-2-cis(O) and Lambda- and Delta -C-1-cis(O) diastereomers, while the Delta -trans(O) diastereomer was only detected in the corresponding eluate. Separation of the obtained diastereomers was performed by chromatography on a Dowex 1 x 4 column. Characterization of the isolated diastereomers was carried out by means of elemental analysis, electronic absorption, circular dichroic, H-1 and C-13 NMR spectra, and by x-ray crystal structure analysis in the case of the Delta -C-1-cis(O) diastereomer. We established the general rule of preference of diasteromers formation in complexes of [Co(L-aa)(2)diamine](+) (L-aa = L-amino acid anion; diamine = 1,2-diaminoethane or 1,3-diaminopropane) type.

AB  - The effect of enlargement of the chelate ring size in Co(III) complexes containing bidentate aminocarboxylato and/or diamine ligands on their R-F values in salting-out chromatography has been investigated on thin layers of silica gel, cellulose, polyacrylonitrile, and CN-modified silica gel. Salting-out was achieved with aqueous solutions of ammonium sulfate, Enlargement of the chelate ring caused a decrease in the R-F values of the complexes. By use of linear regression analysis and the theory of error propagation it was established that the logarithms of the separation factors of the pairs of compounds investigated were either unaffected or changed only slightly with changing concentration of salt in the mobile phase; this could not be established for certain on the basis of R-F values alone. Complete correlation was established between the chromatographic behavior of the complexes and the previously investigated effect of successive enlargement of the rings in cobalt(III) complexes containing hexadentate ligands of the EDTA type. The corresponding separation mechanism of the pairs of compounds investigated was also considered. It was finally established that the regularities mentioned were independent of the adsorbent used.
