New transition metal complex of Cobalt(III) of the ligand (E)-3-(1-(2-aminoethylimino)ethyl)-4-hydroxy- 2H-chromen-2-one, has been synthesized and characterized by IR, UV-Vis, 1H NMR- and 13C NMR-spectroscopy techniques. Single crystal X-ray diffraction reveled a triclinic structure consisting of isolated [Co(III)(C13H13N2O3)2]+ cations with distorted octahedral geometry, 4 counter anions, acetone solvent and water molecules. The crystal cohesion is stabilized by hydrogen bonds.
