Synthesis

edit

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]

SbF5 + K2MnF6 → 4KSbF6 + 2MnF3 + F2

Uses
