Preparation edit

Potassium perrhenate can be produced by the neutralization of potassium hydroxide and perrhenic acid.[2]

 

Properties edit

Potassium perrhenate is a white solid that is sparingly soluble in water and ethanol. It have a tetragonal crystal system with the space group I41/a (No. 88), and lattice constants a = 567.4 pm and c = 1266.8 pm.[2] It is a strong oxidizer.[4]
