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 degrees C. The complex was isolated choromatographically and characterized by elemental analyses, electron absorption and infrared spectroscopy.

Sintetisan je i okarakterisan meridijalni izomer uns-cis-(etilendiamin-N-N'-di-3-propionato)(S-norleucinato)kobalt(III) hemihidrat. Kompleks je dobiven reakcijom natrijum-uns-cis-(etilendiamin-N-N'-di-3-propionato)kobaltata(III) dihidratai S-norleucina na 75 ºC. Kompleks je izolovan hromatografski i okarakterisan elementalnom analizom, elektronsko-apsorpcionom i infracrvenom spektroskopijom.
