Sodium perrhenate (also known as Sodium Rhenate(VII)) is the inorganic compound with the formula NaReO4 It is a white crystalline solid that is soluble in water. It is a common precursor to rhenium compounds. Its structure resembles that of sodium perchlorate and sodium permanganate.

Preparation[edit]

It can be prepared by treatment of rhenium heptoxide with base or by ion exchange from the potassium salt.

Reactions[edit]

It reacts with sodium in ethanol to give nonahydridorhenate.[1] and with polysulfide solutions to give tetrathiorhenate. [2]
