Synthesis and reactions
editRhenium trioxide chloride can be prepared by chlorination of rhenium trioxide:[2]
- 2 ReO3 + Cl2 → 2 ReO3Cl
With Lewis bases (L), rhenium trioxide chloride reacts to form adducts with the formula ReO3ClL2.[3]
The compound hydrolyzes readily to give perrhenic acid.
Structure
editThe compound adopts a tetrahedral structure with Re-O and Re-Cl bond distances of 1.71 and 2.22 Å.[4] In contrast rhenium trioxide fluoride (ReO3F) is polymeric with octahedral Re centers.
