• Resumen

  • Cobalt(III) complexes have been used in the undergraduate inorganic laboratory to demonstrate various techniques in coordination chemistry. This report describes an experiment involving the synthesis and resolution of enantiomeric tris(ethylenediamine)cobalt(III) compounds followed by the analysis of enantiomeric purity by optical rotation and 59Co NMR spectroscopy through the formation of diastereomeric ion pairs.
