Caesium permanganate is the permanganate salt of caesium, with the chemical formula .
Preparation
Caesium permanganate can be formed by the reaction of potassium permanganate and caesium chloride in aqueous solution, followed by concentrating the solution.
Properties Physical
It solubility in water is low: 0.97 g/L at 1 °C, 2.3 g/L at 19 °C, and 12.5 g/L at 59 °C. Its crystal structure is orthorhombic, the same as rubidium permanganate, ammonium permanganate and potassium permanganate.
Thermal degradation Similar to the behavior of potassium permanganate, the two-step decomposition of caesium permanganate leads to caesium manganate, which further breaks down into manganese dioxide, caesium oxide, and oxygen. The decomposition temperature is between 200 and 300 °C. Drift-away oxygen caused an 8% mass loss in the product.
