The mixed uns-cis(beta-diketonato)(1,3-propanediamine-N,N'-diacetato)cobalt(III) complexes (beta-diketonato ligands = 2,4-pentanedione, 1,3-diphenyl-1,3-propanedione and 2,2,6,6-tetramethyl-3,5-heptanedione) were prepared by the reaction of sodium uns-cis-(1,3-propanediamine-N,N'-diacetato)(carbonato)cobaltate(III) and the corresponding symmetrical beta-diketone at 75 degrees C. The complexes were isolated chromatographically and characterized by elemental analysis, infrared and electron absorption spectroscopy.
