Sodium perrhenate (also known as sodium rhenate(VII)) is theinorganic compound with the formulaNaReO4. It is a white salt that is soluble in water. It is a common precursor to otherrhenium compounds. Its structure resembles that ofsodium perchlorate andsodium permanganate.
It can be prepared by treatment ofrhenium heptoxide with base or byion exchange from the potassium salt.[2]
Sodium perrhenate can be prepared from rhenium metal with hydrogen peroxide in the presence of base.[3]
It reacts with sodium in ethanol to givenonahydridorhenate.[2]
Sodium perrhenate has been used as a precursor of rhenium nitrides (such as Re3N, Re2N, Re3N2, ReN2, ReN3, ReN4), which can be used as catalysts for ammonia synthesis and for hydro-denitrogenation.[4]
It can be used to prepareRe2(CO)10.[3]
