This colourless gas is a strong oxidant that was once a candidate oxidizer for rockets. The molecule adopts a <a href="/facts/Square_pyramidal_molecular_geometry/dQDl1IpI">square pyramidal structure</a> with C4v <a href="/facts/Molecular_symmetry/BrDxAkTK">symmetry</a>, as confirmed by its <a href="/facts/Fluorine-19_NMR/uMuD7QbT">high-resolution 19F NMR spectrum</a>. It was first synthesized in 1963. </p>
