Rhenium trioxide chloride is an inorganic compound with the formula ReO
3Cl. It is a colorless, distillable, diamagnetic liquid. It is a rhenium oxychloride.^[1] The material is used as a reagent in the preparation of rhenium compounds.

Synthesis and reactions

Rhenium trioxide chloride can be prepared by chlorination of rhenium trioxide:^[2]

2 ReO
3 + Cl
2 → 2 ReO
3Cl

With Lewis bases (L), rhenium trioxide chloride reacts to form adducts with the formula ReO
3ClL
2.^[3]

The compound hydrolyzes readily to give perrhenic acid.

Structure

The 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 (ReO
3F) is polymeric with octahedral Re centers.
