Iodosyl pentafluoride is an inorganic compound of iodine, fluorine, and oxygen with the chemical formula IOF5.
Synthesis
[edit]- Reaction of iodine heptafluoride with water:[1][2]
- IF7 + H2O → IOF5 + 2 HF
- Reaction of iodine heptafluoride with silicon dioxide:[3][4]
- 2 IF7 + SiO2 → 2 IOF5 + SiF4
Physical properties
[edit]Iodosyl pentafluoride forms a colorless liquid.[5] The molecule of IOF5 is a distorted octahedron O=I(F4)–F.[6] Its melting point 4.5 °C.[3]
Chemical properties
[edit]The compound reacts with graphite to form a black graphite intercalation compound.[7] Iodosyl pentafluoride also forms adducts with arsenic pentafluoride and antimony pentafluoride.[8]
