Rhenium trioxide fluoride is an inorganic compound with the formula {{chem2|ReO3F}}. It is a white, sublimable, diamagnetic solid, although impure samples appear colored. It one of the few oxyfluorides of rhenium, the other major one being rhenium dioxide trifluoride {{chem2|ReO2F3}} . The material has no applications, but it is of some academic interest as a rare example of a trioxide fluoride.
Synthesis and reactions
Rhenium trioxide fluoride can be prepared by fluorination of rhenium trioxide:
:{{chem2|2 ReO3 + F2 -> 2ReO3F}}
With Lewis bases (L) the compound forms adducts with the formula {{chem2|ReO3FL2}}, e.g., L = diethyl ether and acetonitrile.{{cite journal |doi=10.1002/zaac.200500239 |title=Preparation and Structure of Rhenium Fluoride Trioxide ReO3F, and the Polymorphism of Rhenium Trifluoride Dioxide, ReO2F3 |year=2005 |last1=Supeł |first1=Joanna |last2=Marx |first2=Rupert |last3=Seppelt |first3=Konrad |journal=Zeitschrift für anorganische und allgemeine Chemie |volume=631 |issue=15 |pages=2979–2986 }}
