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.{{cite journal |author1=Brown, F. E. |author2=Woods, J. D. ( |title=Preparation and Some Properties of Manganese (II) Chlorate |journal=Proceedings of the Iowa Academy of Science |date=1953 |volume=60 |issue=34 |page=6 |url=https://scholarworks.uni.edu/pias/vol60/iss1/34|access-date=23 August 2021 |publisher=UNI Scholar Works |language=English}}
Preparation
Manganese(II) chlorate was produced by the reaction of manganese(II) sulfate and barium chlorate.{{cite book |author1=R. D. W. Kemmitt |author2=R. D. Peacock |author3=J. C. Bailar |author4=H. J. Emeléus |author5=Ronald Nyholm |editor1-last=Nyholm |editor1-first=Nyholm |title=The Chemistry of Manganese, Technetium and Rhenium |date=January 26, 2016 |publisher=Elsevier Science |isbn=9781483187624 |pages=226 |language=English}} 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.
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.
