Procedure

To a solution of tropolone (244 mg) in methanol is added a solution of cobalt (II) chloride (129 mg) in water and then sodium acetate (164 mg). The precipitate is recovered by filtration and recrystallized from ethanol-ethyl acetate to give 206 mg of tropolone cobalt complex as brown powder.
