摘要：

The complex was prepared by reaction of cis-[Co(phen)2Cl2]Cl.3H2O (phen = phenanthroline) with L-proline at pH 9, isolated by chromatography using an SP-Sephadex C-25 H+ form column, and characterized by elemental analysis, spectroscopy and thermogravimetry. The X-ray crystal structure has also been determined. There are 1.5 independent complex cations, 1.5 ClO4- anions and two H2O molecules in each asymmetric unit, and two complex cations of similar structure in the crystal. There is a crystallographic C2 symmetry in the first of these. In the octahedral coordination sphere of the metal the oxygen and nitrogen chelating prolinato ligands are arranged in the trans-N,N form.
