Molecules with two binding pairs and three lone pairs are arranged in a trigonal bipyramidal shape with the three pairs 
lonely in equatorial Without taking into account the lone pairs we obtain a linear geometry.
An example of this geometry is found in the triiodide ion, I 3 - 
The location of the lone pairs in equatorial minimizes the repulsions between them, as they are located at 120º.
