Potassium hexafluoroantimonate is an inorganic chemical compound with the chemical formula KSbF6. [2]
Potassium hexafluoroantimonate can be prepared by reacting potassium pyroantimonate K2H2Sb2O7 with hydrogen fluoride or by treating the product of the reaction of a mixture of solid antimony(III) oxide and potassium hydroxide with hydrogen peroxide solution (30%) with hydrochloric acid (48%). [3]
Also, the compound can be prepared by reacting antimony pentafluoride and potassium hexafluoromanganate. [4]
Potassium hexafluoroantimonate is used as a pharmaceutical intermediate. [5]
Potassium hexafluoroaluminate can cause violent reactions with strong acids and oxidizing agents. [6]
