A new, more efficient procedure for the preparation of potassium tris(malonto)cobaltate(III) dihydrate

Article abstract of DOI:10.1080/00945719909351710

A new, very efficient and elegant procedure for the preparation of potassium tris(malonato)cobaltate(III) dihydrate, starting from Co(OH)₃ and potassium hydrogenmalonate, is presented. The most important advantages of this procedure, in comparison to the previously reported ones, are: a relatively short time required, saving of the reagents and solvents, and a very good yield of pure product. The identification of the obtained complex was carried out by elemental analyses, electronic absorption and IR spectroscopy. The spectral data are in accordance with the previously reported literature data. Analogous procedure was also preliminary tested for the preparation of the corresponding tris(oxalato)-and tris(succinato)cobaltate(III). Finally, the described complex can be used as a starting material for the preparation of one mixed ligand Co(III) complex.
