Manganese(II) chlorate

Manganese(II) chlorate is an unstable chemical compound with the formula Mn(ClO3)2. It is unstable even in dilute solution. As a hexahydrate, it is solid below −18°C. Above this it melts, to form an extremely explosive pink liquid.[2]

Preparation

Manganese(II) chlorate was produced by the reaction of manganese(II) sulfate and barium chlorate.[3] The water was removed by boiling in vacuum. Then the temperature was lowered to -80°C which resulted in a pink solid. Then it was cleaned with liquid nitrogen and potassium hydroxide to remove the decomposition products.[2]

Properties

Manganese(II) chlorate forms the hexahydrate when solid, the water that cannot be removed. It decomposes above 6°C, to manganese(IV) oxide, chlorine dioxide, and water. In liquid form it is very viscous and extremely explosive. When heated to room temperature, it explodes with a sharp report.[2]
