Resumo

PARADA, JOSÉ et al. ISOLATION AND CHARACTERIZATION OF COBALT (III) TRIS-D-AMINOSUGARS. J. Chil. Chem. Soc. [online]. 2006, vol.51, n.2, pp.879-881. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072006000200009.

Mixed complexes of aminosugars and 1,10-phenanthroline (phen) with cobalt(III), with the composition Co(III)(phen)2sugar, disproportionate in aqueous solution in approximately one month, giving non ionic tris-aminosugar complexes. The complexes with a-D-glucosamine, a-D-galactosamine and b-D-mannosamine have the L-configuration at Co(III) with facial isomerism, on the bases of molecular composition and absorption and circular dichroism spectra
