#sp^3d#

Explanation:

The easiest way to determine this is to draw the lewis structure of the species. What's important here is knowing that the species, #I# can become hypervalent, or that is, it will disobey the octet rule by expanding its valency to accept more than eight electron around it.

Another good example of a species which does this is #XeF_4#.

Consider below:

Remember when forming hybrid orbitals, we always know that we must:

use #n# atomic orbital to make #n# hybrid orbitals

and

for #n=5# we know that we make #sp^3d# hybrids.
