All stable hexatomic and octatomic interhalogens involve a heavier halogen combined with five or seven fluorine atoms. Unlike the other halogens, fluorine atoms have high electronegativity and small size which is able to stabilize them.
*'''[[Chlorine pentafluoride]]''' (ClF<sub>5</sub>) is a colourless gas, made by reacting chlorine trifluoride with fluorine at high temperatures and high pressures. It reacts violently with water and most [[metals]] and [[Nonmetal (chemistry)|nonmetal]]s.
*'''[[Bromine pentafluoride]]''' (BrF<sub>5</sub>) is a colourless fuming liquid, made by reacting bromine trifluoride with fluorine at 200&nbsp;°C. It is physically stable, but decomposes violently on contact with water, organic substances, and most metals and [[Nonmetal (chemistry)|nonmetal]]s.
*'''[[Iodine pentafluoride]]''' (IF<sub>5</sub>) is a colourless liquid, made by reacting iodine pentoxide with fluorine, or iodine with [[silver(II) fluoride]]. It is highly reactive, even slowly with glass. It reacts with water to form [[hydrofluoric acid]] and with fluorine gas to form [[iodine heptafluoride]]. The molecule has the form of a [[Square pyramidal molecular geometry|tetragonal pyramid]].
