The dihydrate is prepared by combining potassium permanganate and manganese(II) acetate in acetic acid. [3] Addition of acetic anhydride to the reaction produces the anhydrous form. [ 1 ] [ 2 ] It is also synthesized by electrochemical method starting from Mn(OAc) 2 .
The anhydrous material and dihydrate Mn(CH 3 CO 2) 2 ·2H 2 O are coordination polymers. The dihydrate has been characterized by X-ray crystallography. Each Mn(II) center is surrounded by six oxygen centers provided by aquo ligands and acetates. Subunit of the structure of the dihydrate of manganese(II) acetate. [5]
Manganese-mediated coupling reactions are radical coupling reactions between enolizable carbonyl compounds and unsaturated compounds initiated by a manganese(III) salt, typically manganese(III) acetate. Copper(II) acetate is sometimes used as a co-oxidant to assist in the oxidation of intermediate radicals to carbocations.
Mn(acac) 3 has been prepared by the comproportionation of the manganese(II) compound Mn(acac) 2 with potassium permanganate in the presence of additional acetylacetone. [12] Alternatively the direct reaction of acetylacetone with potassium permanganate. [13] In terms of electronic structure, Mn(acac) 3 is high spin.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Potassium acetate (as a substitute for calcium chloride or magnesium chloride) can be used as a deicer to remove ice or prevent its formation. It offers the advantage of being less aggressive on soils and much less corrosive: [5] for this reason, it is preferred for airport runways although it is more expensive.
