Synthesis and characterization of meridional isomer of uns-cis-(ethylenediamine-N-N'-di-3-propionato)-(S-norleucinato)cobalt(III) semihydrate

Abstract

The meridional geometrical isomer of uns-cis-(ethylenediamine-N-N'-di-3-propionato)(S-norleucinato)cobalt(III) complex has been prepared by the reaction of sodium uns-cis-(ethylenediamine-N-N'-di-3-propionato)(carbonato)cobaltate(III) with S-norleucine at 75°C. The complex was isolated choromatographically and characterized by elemental analyses, electron absorption and infrared spectroscopy
