Francium chloride is a radioactive chemical compound with the formula FrCl. It is a salt predicted to be a white solid and is soluble in water.
The relativistic destabilisation of the 6p 3/2 spinor may make francium compounds in oxidation states higher than +1 possible, such as [Fr V F 6] −; but this has not been experimentally confirmed. [5] Francium perchlorate is produced by the reaction of francium chloride and sodium perchlorate.
