%X When the [Co(en)2(H2O)2]3+ ion is allowed to react with the sodium salt of acetylpyruvic acid or its methyl ester in aqueous solution at 80ºC, hydrolysis of the &#946;-diketone occurs and [Co(en)2(ox)]I2 is isolated by the addition of potassium iodide. The method of preparation and characterization of [Co(en)2(ap)]I and [Co(en)2(map)]I2 are described. Reactions involving the corresponding tetraammine and cis-&#945;-triethylenetetramine cobalt(111) complexes are also described.
