AB  - Two compounds, [Co-III(L)(py)(3)][Co-II(PY)Cl-3]. EtOH and [Co-III(L)(PY)(3)]I-3 (H2L = salicylaldehyde S-methylisothiosemicarbazone, py = pyridine), were synthesized and the crystal structures deter-mined by single-crystal X-ray diffraction. In both structures the geometries of the cation are very similar to a thiosemicarbazide-based ligand coordinated in the mer configuration. The axial pyridines are in mutual perpendicular orientation. the angles between the planes being 85.3(2) and 82.5(2)degrees. The plane of the equatorial pyridine is tilted with respect to the equatorial plane by about 40 degrees. The orientations of the pyridines were studied in model systems by quantum chemistry calculations. It was shown that the interactions between axial and equatorial pyridines are responsible for the orientation of pyridines in the complex cation: consequently, there are very similar geometries of the complex cation in both crystal structures. The compounds were also characterized by elemental analysis, molar conductivity, magnetic susceptibility and electronic absorption spectra. (C) 2001 Elsevier Science Ltd. All rights reserved.

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.
