Isolation and characterization of cobalt(III)tris-D-glucosamine

Abstract

Mixed bis-phenanthroline Co(III) complexes with amino sugars disproportionate over a period of months, giving non-ionic tris(aminosugar)complexes. The complex with alpha-D-glucosamine has the Lambda-configuration with facial isomerism on the base of molecular composition and absorption and circular dichroism spectra.
