SYNTHESIS AND REACTIVITY IN INORGANIC AND METAL-ORGANIC CHEMISTRY
A new, very efficient and elegant procedure for the preparation of potassiu
m tris(malonato)cobaltate(III) dihydrate, starting from Co(OH)(3) and potas
sium 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 carri
ed out by elemental analyses, electronic absorption and IR spectroscopy. Th
e spectral data are in accordance with the previously reported literature d
ata. Analogous procedure was also preliminary tested for the preparation of
the corresponding tris(oxalato)- and tris(succinato)cobaltate(III). Finall
y, the described complex can be used as a starting material for the prepara
tion of one mixed ligand Co(III) complex.
