IBr3 - Iodine Tribromide:

First draw the Lewis dot structure:
IBr3 Lewis Structure
Electron geometry: trigonal bipyramidal. Hybridization: sp3d

Then draw the 3D molecular structure using VSEPR rules:
  Click and drag the molecle to rotate it.

The molecular geometry of Br3 is T-shaped with an asymmetric charge distribution on the central atom.
Therefore this molecule is polar.

This is somewhat of a rare molecule (perhaps difficult to manufacture). Here is a similar molecule (theoretically):
Iodine Trifluoride on Wikipedia.
