It's tough to draw these structures on the boards.In fact, it's impossible to draw this on the boards. Start with what I have above. Each F should have four (4) pairs of electrons, a pair to the left, a pair on top, a pair to the right, and a pair on the bottom. That uses 32 electrons and places 4 pairs (8 total) around I. There are 36 electrons to be placed; therefore, add 2 pairs (4 total( around the I atom. Then add a single negative charge to the entire IF4-
If I see something wrong with the structure I've drawn, I will post a note as an appendage.
What is the Lewis structure for IF4-?

You see the problem is spacing. Ignore the  . Look for the dots. They, together with the explanation I offered, should be the correct structure.
