What is the molecular geometry of IF5?


Quick Answer

The molecular geometry of IF5, also known as iodine pentafluoride, is a pyramid with a square base surrounding a central iodine atom. Each of the corners of the pyramid is a fluorine atom.

Full Answer

The angle between each of the bonds in the molecule is 90 degrees for the four fluorine atoms making up the base of the pyramid, and 180 degrees for the single fluorine atom making up the pyramid's point. The two-dimensional structure of iodine pentafluoride is written out as a central iodine atom surrounded by five fluoride atoms in a star shape resembling an asterisk, but this is for convenience and does not correspond to the true shape of the molecule or the bond angles involved.

Bromine pentafluoride has a very similar shape to iodine pentafluoride.
