ICl₅ : First draw the Lewis dot structure:

Electron geometry: octahedral. Hybridization: sp³d²

Then construct the 3D geometry using VSEPR rules:


Decision:
The molecular geometry of ICl₅ is square pyramid with an asymmetric electron region distribution.
Therefore this molecule is polar.

Iodine pentachloride is a rare molecule, but here is one similar: Iodine Pentafluoride on Wikipedia.
