• Resumen

  • 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
